FIELD OF THE INVENTION <br><br>
The invention relates generally to compounds with anti-cancer activity. <br><br>
10 BACKGROUND OF THE INVENTION <br><br>
Improving the delivery of drugs and other agents to target cells and tissues has been the focus of considerable research for many years. Though many attempts have been made to develop effective methods for importing biologically active molecules into cells, both in vivo and in vitro, none has 15 proved to be entirely satisfactoiy. Optimizing the association of the drug with its intracellular target, while minimizing intercellular redistribution of the drug, e.g., to neighboring cells, is often difficult or inefficient <br><br>
Most agents currently administered to a patient parenterally are not targeted, resulting in systemic delivery of the agent to cells and tissues of the 20 body where it is unnecessary, and often undesirable. This may result in adverse drug side effects, and often limits the dose of a drug (e.g., glucocorticoids and other anti-inflammatory drugs) that can be administered. By comparison, although oral administration of drugs is generally recognized as a convenient and economical method of administration, oral administration can result in either (a) 25 uptake of the drug through the cellular and tissue barriers, e.g., blood/brain, epithelial, cell membrane, resulting in undesirable systemic distribution, or (b) temporary residence of the drug within the gastrointestinal tract Accordingly, a major goal has been to develop methods for specifically targeting agents to cells and tissues. Benefits of such treatment includes avoiding the general 30 physiological effects of inappropriate delivery of such agents to other cells and tissues, such as uninfected cells. <br><br>

SUMMARY OF THE INVENTION <br><br>
Intracellular targeting may be achieved by methods and compositions that allow accumulation or retention of biologically active agents inside cells. The present invention provides novel phosphonate containing analogs of immunomodulatory (e.g., immunosuppressant) compounds. These compounds possess the utilities of the related immuno-modulatory compounds, but due to the presence of the phosphonate group(s) they typically provide cellular accumulation of the phosphonate compound. Thus, compounds of the invention may demonstrate improved immuno-modulatory properties, pharmacokinetic properties, oral bioavailability, potency, or extended effective half-life in vivo, or a combination thereof. The compounds of the invention may also have distinct resistance profiles, fewer side effects, less complicated dosing schedules, or have increased oral activity. <br><br>
The present invention relates generally to the accumulation or retention of therapeutic compounds inside cells. The invention is more particularly related to attaining high concentrations of phosphonate-containing molecules in target cells. Such effective targeting may be applicable to a variety of therapeutic formulations and procedures. <br><br>

DEFINITIONS <br><br>
Unless stated otherwise, the following terms and phrases as used herein 5 are intended to have the following meanings: <br><br>
When tradenames are used herein, applicants intend to independently include the tradename product and the active pharmaceutical ingredients) of the tradename product. <br><br>
' "Bioavailability" is the degree to which the pharmaceutically active agent 10 becomes available to the target tissue after the agent's introduction into the body. Enhancement of the bioavailability of a pharmaceutically active agent can provide a more efficient and effective treatment for patients because, for a given dose, more of the pharmaceutically active agent will be available at the targeted tissue sites. <br><br>
15 The terms "phosphonate" and "phosphonate group" include functional groups or moieties within a molecule that comprises a phosphorous that is 1) <br><br>
single-bonded to a carbon, 2) double-bonded to a heteroatom, 3) single-bonded to a heteroatom, and 4) single-bonded to another heteroatom, wherein each heteroatom can be the same or different. The terms "phosphonate" and <br><br>
20 "phosphonate group" also include functional groups or moieties that comprise a phosphorous in the same oxidation state as the phosphorous described above, as well as functional groups or moieties that comprise a prodrug moiety that can separate from a compound so that the compound retains a phosphorous having the characteristics described above. For example, the terms "phosphonate" and <br><br>
25 "phosphonate group" include phosphonic acid, phosphonic monoester, <br><br>
phosphonic diester, phosphonamidate, andphosphonthioate functional groups. <br><br>
In one specific embodiment of the invention, the terms "phosphonate" and <br><br>
"phosphonate group" include functional groups or moieties within a molecule that comprises a phosphorous that is 1) single-bonded to a carbon, 2) double- <br><br>
30 bonded to an oxygen, 3) single-bonded to an oxygen, and 4) single-bonded to another oxygen, as well as functional groups or moieties that comprise a prodrug moiety that can separate from a compound so that the compound retains a phosphorous having such characteristics. In another specific embodiment of the <br><br>

invention, the terms "phosphonate" and "phosphonate group" include functional groups or moieties within a molecule that comprises a phosphorous that is 1) single-bonded to a carbon, 2) double-bonded to an oxygen, 3) single-bonded to an oxygen or nitrogen, and 4) single-bonded to another oxygen or nitrogen, as 5 well as functional groups or moieties that comprise a prodrug moiety that can separate from a compound so that the compound retains a phosphorous having such characteristics. <br><br>
The term "prodrug" as used herein refers to any compound that when administered to a biological system generates the drug substance, i.e. active 10 ingredient, as a result of spontaneous chemical rcaction(s), enzyme catalyzed chemical reaction(s), photolysis, and/or metabolic chemical reaction(s). A prodrug is thus a covalently modified analog or latent form of a therapeutically-active compound. <br><br>
"Prodrug moiety" refers to a labile functional group which separates from 15 the active inhibitory compound during metabolism, systemically, inside a cell, by hydrolysis, enzymatic cleavage, or by some other process (Bundgaard, Hans, "Design and Application of Prodrugs" in A Textbook of Drug Design and Development (1991), P. Krogsgaard-Larsen and H. Bundgaard, Eds. Harwood Academic Publishers, pp. 113-191). Enzymes which are capable of an 20 enzymatic activation mechanism with the phosphonate prodrug compounds of the invention include, but are not limited to, amidases, esterases, microbial enzymes, phospholipases, cholinesterases, and phosphotases. Prodrug moieties can serve to enhance solubility, absorption and lipophilicity to optimize drug delivery, bioavailability and efficacy. A prodrug moiety may include an active 25 metabolite or drug itself. <br><br>
Exemplary prodrug moieties include the hydrolytically sensitive or labile acyloxymethyl esters -CH20C(=0)R9 and acyloxymethyl carbonates -CH20C(=0)0R9 where R9 is Ci-Cg alkyl, C1-C6 substituted alkyl, C6-C20 aryl or CS-C20 substituted aryl. The acyloxyalkyl ester was first used as a prodrug 30 strategy for carboxylic acids and then applied to phosphates and phosphonates by Farquhar et al. (1983) J. Pharm. Sci. 72: 324; also US Patent Nos. 4816570, 4968788, 5663159 and 5792756. Subsequently, the acyloxyalkyl ester was used to deliver phosphonic acids across cell membranes and to enhance oral <br><br>

WO 2004/096236 PCT/US2004/013143 <br><br>
bioavailability. A close variant of the acyloxyalkyl ester, the alkoxycarbonyloxyalkyl ester (carbonate), may also enhance oral bioavailability as a prodrug moiety in the compounds of the combinations of the invention. An exemplary acyloxymethyl ester is pivaloyloxymethoxy, (POM) 5 -CH2OC(=O)C(CH:0j. An exemplary acyloxymethyl carbonate prodrug moiety is pivaloyloxymethylcarbonate (PQC) -CIl20C(=0)0C(CIl3)3. <br><br>
The phosphonate group may be a phosphonate prodrug moiety. The prodrug moiety may be sensitive to hydrolysis, such as, but not limited to a pivaloyloxymethyl carbonate (POC) or POM group. Alternatively, the prodrug 10 moiety may be sensitive to enzymatic potentiated cleavage, such as a lactate ester or a phosphonamidate-ester group. <br><br>
Aryl esters of phosphorus groups, especially phenyl esters, are reported to enhance oral bioavailability (De Lombaert et al. (1994) J. Med. Chem. 37: 498). Phenyl esters containing a carboxylic ester ortho to the phosphate have 15 also been described (Khamnei and Torrence, (1996) J. Med. Chem. 39:4109-4115). Benzyl esters are reported to generate the parent phosphonic acid. In some cases, substituents at the oriho-or para-position may accelerate the hydrolysis. Benzyl analogs with an acylated phenol or an alkylated phenol may generate the phenolic compound through the action of enzymes, e.g., esterases, 20 oxidases, etc., which in turn undergoes cleavage at the benzylic C-0 bond to generate the phosphoric acid and the quinone methide intermediate. Examples of this class of prodrugs are described by Mitchell et al. (1992) J. Chem. Soc. Perldn Trans. II2345; Glazier WO 91/19721. Still other benzylic prodrugs have been described containing a carboxylic ester-containing group attached to the 25 benzylic methylene (Glazier WO 91/19721). Thio-containing prodrugs are reported to be useful for the intracellular delivery of phosphonate drugs. These proesters contain an ethylthio group in which the thiol group is either esterified with an acyl group or combined with another thiol group to form a disulfide. Deesterification or reduction of the disulfide generates the free thio intermediate 30 which subsequently breaks down to the phosphoric acid and episulfide (Puech et al. (1993) Antiviral Res., 22: 155-174; Benzaria et al. (1996) J. Med. Chem. 39: 4958). Cyclic phosphonate esters have also been described as prodrugs of phosphorus-containing compounds (Erion et al., US Patent No. 6312662). <br><br>

"Protecting group" refers to a moiety of a compound, that masks or alters the properties of a functional group or the properties of the compound as a whole. Chemical protecting groups and strategies for protection/deprotection are well known in the art. See e.g., Protective Groups in Organic Chemistry, 5 Theodora W. Greene, John Wiley Si Sons, Inc., New York, 1991. Protecting groups are often utilized to mask the reactivity of certain functional groups, to assist in the efficiency of desired chemical reactions, e.g., making and breaking chemical bonds in an ordered and planned fashion. Protection of functional groups of a compound alters other physical properties besides the reactivity of 10 the protected functional group, such as the polarity, lipophilicity <br><br>
(hydrophobicity), and other properties which can be measured by common analytical tools. Chemically protected intermediates may themselves be biologically active or inactive. <br><br>
Protected compounds may also exhibit altered, and in some cases, 15 optimized properties in vitro and in vivo, such as passage through cellular membranes and resistance to enzymatic degradation or sequestration. In this role, protected compounds with intended therapeutic effects may be referred to as prodrugs. Another function of a protecting group is to convert the parental drug into a prodrug, whereby the parental drug is released upon conversion of ( 20 the prodrug in vivo. Because active prodrugs may be absorbed more effectively than the parental drug, prodrugs may possess greater potency in vivo than the parental drug. Protecting groups are removed either in vitro, in the instance of chemical intermediates, or in vivo, in the case of prodrugs. With chemical intermediates, it is not particularly important that the resulting products after 25 deprotection, e.g., alcohols, be physiologically acceptable, although in general it is more desirable if the products are pharmacologically innocuous. <br><br>
Any reference to any of the compounds of the invention also includes a reference to a physiologically acceptable salt thereof. Examples of physiologically acceptable salts of the compounds of the invention include salts 30 derived from an appropriate base, such as an alkali metal (for example, sodium), an alkaline earth (for example, magnesium), ammonium and NX*}"1" (wherein X is C1-C4 alkyl). Physiologically acceptable salts of an hydrogen atom or an amino group include salts of organic carboxylic acids such as acetic, benzoic, lactic, <br><br>

Physiologically 5 acceptable salts of a compound of an hydroxy group include the anion of said compound in combination with a suitable cation such as Na+ and NX4 " (wherein X is independently selected from H or a C1-C4 alkyl group). <br><br>
For therapeutic use, salts of active ingredients of the compounds of the invention will be physiologically acceptable, i.e. they will be salts derived from a 10 physiologically acceptable acid or base. However, salts of acids or bases which are not physiologically acceptable may also find use, for example, in the preparation or purification of a physiologically acceptable compound. All salts, whether or not derived form a physiologically acceptable acid or base, are within the scope of the present invention. <br><br>

"Carbocycle" refers to a saturated, unsaturated or aromatic ring having 3 to 7 carbon atoms as a monocycle, 7 to 12 carbon atoms as a bicycle, and up to about 20 carbon atoms as a polycycle. Monocyclic carbocycles have 3 to 6 ring 5 atoms, still more typically 5 or 6 ring atoms. Bicyclic carbocycles have 7 to 12 ring atoms, e.g., arranged as abicyclo [4,5], [5,5], [5,6] or [6,6] system, or 9 or 10 ring atoms arranged as a bicyclo [5,6] or [6,6] system. Examples of monocyclic carbocycles include cyclopropyl, cyclobutyl, cyclopentyl, 1-cyclopent-l-enyl, 1 -cyclopent-2-enyl, 1 -cyclopent-3-enyl, cyclohexyl, 1-10 cyclohex-l-enyl, l-cyclohex-2-enyl, l-cyclohex-3-enyl, phenyl, spiryl and naphthyl. <br><br>
"Linker" or "link" refers to a chemical moiety comprising a covalent bond or a chain or group of atoms that covalently attaches a phosphonate group to a drug. Linkers include portions of substituents A1 and A3, which include 15 moieties such as: repeating units of alkyloxy (e.g., polyethylenoxy, PEG, <br><br>
polymethyleneoxy) and alkylamino (e.g., polyethyleneamino, Jeffamine™); and diacid ester and amides including succinate, succinamide, diglycolate, malonate, and caproamide. <br><br>
The term "chiral" refers to molecules which have the property of non-20 superimposability of the mirror image partner, while the term "achiral" refers to molecules which are superimposable on their mirror image partner. <br><br>
The term "stereoisomers" refers to compounds which have identical chemical constitution, but differ with regard to the arrangement of the atoms or groups in space. <br><br>
25 "Diastereomer" refers to a stereoisomer with two or more centers of chirality and whose molecules are not mirror images of one another. Diastereomers have different physical properties, e.g., melting points, boiling points, spectral properties, and reactivities. Mixtures of diastereomers may separate under high resolution analytical procedures such as electrophoresis and 30 chromatography. <br><br>
"Enantiomers" refer to two stereoisomers of a compound which are non-superimposable mirror images of one another. <br><br>

The term "treatment" or "treating," to the extent it relates to a disease or condition includes preventing the disease or condition from occurring, inhibiting the disease or condition, eliminating the disease or condition, and/or relieving one or more symptoms of the disease or condition. <br><br>
5 Stereochemical definitions and conventions used herein generally follow <br><br>
S. P. Parker, Ed., McGraw-Hill Dictionary of Chemical Terms (1984) McGraw-Hill Book Company, New York; and Eliel, E. and Wilen, S., Stereochemistry of Organic Compounds (1994) John Wiley & Sons, Inc., New York. Many organic compounds exist in optically active forms, i.e., they have the ability to rotate the 10 plane of plane-polarized light. In describing an optically active compound, the prefixes D and L or R and S are used to denote the absolute configuration of the molecule about its chiral center(s). The prefixes d and 1 or (+) and (-) are employed to designate the sign of rotation of plane-polarized light by the compound, with (-) or 1 meaning that the compound is levorotatory. A 15 compound prefixed with (+) or d is dextrorotatory. For a given chemical structure, these stereoisomers are identical except that they are mirror images of one another. A specific stereoisomer may also be referred to as an enantiomer, and a mixture of such isomers is often called an enantiomeric mixture. A 50:50 mixture of enantiomers is referred to as a racemic mixture or a racemate, which 20 may occur where there has been no stereoselection or stereospecificity in a chemical reaction or process. The terms "racemic mixture" and "racemate" refer to an equimolar mixture of two enantiomeric species, devoid of optical activity. <br><br>
Protecting Groups <br><br>
In the context of the present invention, protecting groups include prodrug 25 moieties and chemical protecting groups. <br><br>
Protecting groups are available, commonly known and used, and are optionally used to prevent side reactions with the protected group during synthetic procedures, i.e. routes or methods to prepare the compounds of the invention. For the most part the decision as to which groups to protect, when to <br><br>
30 do so, and the nature of the chemical protecting group "PG" will be dependent upon the chemistry of the reaction to be protected against (e.g., acidic, basic, <br><br>
oxidative, reductive or other conditions) and the intended direction of the synthesis. The PG groups do not need to be, and generally are not, the same if <br><br>

WO 2004/096236 PCT/US2004/013143 <br><br>
the compound is substituted with multiple PG. hi general, PG will be used to protect functional groups such as carboxyl, hydroxyl, thio, or amino groups and to thus prevent side reactions or to otherwise facilitate the synthetic efficiency. The order of deprotection to yield free, deprotected groups is dependent upon the 5 intended direction of the synthesis and the reaction conditions to be encountered, and may occur in any order as determined by the artisan. <br><br>
Various functional groups of the compounds of the invention may be protected. For example, protecting groups for -OH groups (whether hydroxyl, carboxylic acid, phosphonic acid, or other functions) include "ether- or ester-10 forming groups". Ether- or ester-forming groups are capable of functioning as chemical protecting groups in the synthetic schemes set forth herein. However, some hydroxyl and thio protecting groups are neither ether- nor ester-forming groups, as will be understood by those skilled in the art, and are included with amides, discussed below. <br><br>
15 A very large number of hydroxyl protecting groups and amide-forming groups and corresponding chemical cleavage reactions are described in Protective Groups in Organic Synthesis, Theodora W. Greene (John Wiley & Sons, Inc., New York, 1991, ISBN 0-471-62301-6) ("Greene"). See also Kocienski, Philip J.; Protecting Groups (Georg Thieme Verlag Stuttgart, New 20 York, 1994), which is incorporated by reference in its entirety herein. In particular Chapter 1, Protecting Groups: An Overview, pages 1-20, Chapter 2, Hydroxyl Protecting Groups, pages 21-94, Chapter 3, Diol Protecting Groups, pages 95-117, Chapter 4, Carboxyl Protecting Groups, pages 118-154, Chapter 5, Carbonyl Protecting Groups, pages 155-184. For protecting groups for 25 carboxylic acid, phosphonic acid, phosphonate, sulfonic acid and other protecting groups for acids see Greene as set forth below. Such groups include by way of example and not limitation, esters, amides, hydrazides, and the like. <br><br>
Ether- and Ester-forming protecting groups 30 Ester-forming groups include: (1) phosphonate ester-forming groups, <br><br>
such as phosphonamidate esters, phosphorothioate esters, phosphonate esters, and phosphon-bis-amidates; (2) carboxyl ester-forming groups, and (3) sulphur ester-forming groups, such as sulphonate, sulfate, and sulfinate. <br><br>

The phosphonate moieties of the compounds of the invention may or may not be prodrug moieties, i.e. they may or may not be susceptible to hydrolytic or enzymatic cleavage or modification. Certain phosphonate moieties are stable under most or nearly all metabolic conditions. For example, a 5 dialkylphosphonate. where the alkyl groups are two or more carbons, may have appreciable stability in vivo due to a slow rate of hydrolysis. <br><br>
Within the context of phosphonate prodrug moieties, a large number of structurally-diverse prodrugs have been described for phosphonic acids (Freeman and Ross in Progress in Medicinal Chemistry 34:112-147 (1997)) and 10 are included within the scope of the present invention. An exemplary phosphonate ester-forming group is the phenyl carbocycle in substructure A3 having the formula: <br><br>
15 the phenyl carbocycle is substituted with 0 to 3 R2 groups. Where Yi is O, a lactate ester is formed, and where Yi is N^Ra), N(OR2) or N(N(R2)2, a phosphonamidate ester results. <br><br>
In its ester-forming role, a protecting group typically is bound to any acidic group such as, by way of example and not limitation, a -CO2H or 20 -C(S)OH group, thereby resulting in -C02RX where Rx is defined herein. Also, Rx for example includes the enumerated ester groups of WO 95/07920. <br><br>
Examples of protecting groups include: <br><br>
c3-c12 heterocycle (described above) or aryl. These aromatic groups optionally are polycyclic or monocyclic. Examples include phenyl, spiryl, 2-25 and 3-pyrrolyl, 2- and 3-thienyl, 2- and 4-imidazolyl, 2-, 4- and 5-oxazolyl, 3-and 4-isoxazolyl, 2-, 4- and 5-thiazolyl, 3-, 4- and 5-isothiazolyl, 3- and 4- <br><br>

In some claims the protected acidic group is an ester of the acidic group and is the residue of a hydroxyl-containing functionality, hi other claims, an amino compound is used to protect the acid functionality. The residues of suitable hydroxyl or amino-containing functionalities are set forth above or are 5 found in WO 95/07920. Of particular interest are the residues of amino acids, amino acid esters, polypeptides, or aryl alcohols. Typical amino acid, <br><br>
polypeptide and carboxyl-esterified amino acid residues are described on pages 11-18 and related text of WO 95/07920 as groups LI or L2. WO 95/07920 expressly teaches the amidates of phosphonic acids, but it will be understood that 10 such amidates are formed with any of the acid groups set forth herein and the amino acid residues set forth in WO 95/07920. <br><br>
Typical esters for protecting acidic functionalities are also described in WO 95/07920, again understanding that the same esters can be formed with the acidic groups herein as with the phosphonate of the '920 publication. Typical 15 ester groups are defined at least on WO 95/07920 pages 89-93 (under R^l or r35)5 the table on page 105, and pages 21-23 (asR). Of particular interest are esters of unsubstituted aryl such as phenyl or arylalkyl such benzyl, or hydroxy-, halo-, alkoxy-, carboxy- and/or alkylestercarboxy-substituted aryl or alkylaryl, especially phenyl, ortho- ethoxyphenyl. or C1-c4 alkylestercarboxyphenyl 20 (salicylate C1 -C12 alkylesters). <br><br>
The protected acidic groups, particularly when using the esters or amides of WO 95/07920, are useful as prodrugs for oral administration. However, it is not essential that the acidic group be protected in order for the compounds of this invention to be effectively administered by the oral route. When the compounds 25 of the invention having protected groups, in particular amino acid amidates or substituted and unsubstituted aryl esters are administered systemically or orally they are capable of hydro lytic cleavage in vivo to yield the free acid. <br><br>
One or more of the acidic hydroxyls are protected. If more than one acidic hydroxyl is protected then the same or a different protecting group is 30 employed, e.g., the esters may be different or the same, or a mixed amidate and ester may be used. <br><br>
Typical hydroxy protecting groups described in Greene (pages 14-118) include substituted methyl and alkyl ethers, substituted benzyl ethers, silyl <br><br>

Amino acid and polypeptide protecting group and conjugates <br><br>
An amino acid or polypeptide protecting group of a compound of the invention has the structure R15NHCH(R16)C(0)-, where R15 is H, an amino acid or polypeptide residue, or R5, and R16 is defined below. <br><br>
20 R16 is lower alkyl or lower alkyl (ci-cg) substituted with amino, <br><br>
carboxyl, amide, carboxyl ester, hydroxyl, C6-C7 aryl, guanidinyl, imidazolyl, indolyl, sulfhydryl, sulfoxide, and/or alkylphosphate. R10 also is taken together with the amino acid a N to form a proline residue (R10 = -CH2)3-). However, R10 is generally the side group of a naturally-occurring amino acid such as H, -25 CH3, -CH(CH3)2, -CH2-CH(CH3)2, -chcii3-ch2-ch3, -CH2-C6H5! -CH2CH2- <br><br>

Another set of protecting groups include the residue of an amino-containing compound, in particular an amino acid, a polypeptide, a protecting group, -NHSO2R, NHC(0)R, -N(R)2, NH2 or -NH(R)(H), whereby for example a carboxylic acid is reacted, i.e. coupled, with the amine to form an amide, as in 5 C(0)NR-2. A phosphonic acid may be reacted with the amine to form a phosphonamidate, as in -P(0)(0R)(NR2). <br><br>
In general, amino acids have the structure R17C(0)CH(R16)NH-, where R17 is -OH, -OR, an amino acid or a polypeptide residue. Amino acids are low molecular weight compounds, on the order of less than about 1000 MW and 10 which contain at least one amino or imino group and at least one carboxyl group. Generally the amino acids will be found in nature, i.e., can be detected in biological material such as bacteria or other microbes, plants, animals or man. Suitable amino acids typically are alpha amino acids, i.e. compounds characterized by one amino or imino nitrogen atom separated from the carbon 15 atom of one carboxyl group by a single substituted or unsubstituted alpha carbon atom. Of particular interest are hydrophobic residues such as mono-or di-alltyl or aryl amino acids, cycloalkylamino acids and the like. These residues contribute to cell permeability by increasing the partition coefficient of the parental drug. Typically, the residue does not contain a sulfhydryl or guanidino 20 substituent. <br><br>
Naturally-occurring amino acid residues are those residues found naturally in plants, animals or microbes, especially proteins thereof. <br><br>
Polypeptides most typically will be substantially composed of such naturally-occurring amino acid residues. These amino acids are glycine, alanine, valine, 25 leucine, isoleucine, serine, threonine, cysteine, methionine, glutamic acid, <br><br>
aspartic acid, lysine, hydroxylysine, arginine, histidine, phenylalanine, tyrosine, , tryptophan, proline, asparagine, glutamine and hydroxyproline. Additionally, unnatural amino acids, for example, valanine, phenylglycine and homoarginine are also included. Commonly encountered amino acids that are not gene-30 encoded may also be used in the present invention. All of the amino acids used in the present invention may be either the D- or L- optical isomer. In addition, other peptidomimetics are also useful in the present invention.

When protecting groups are single amino acid residues or polypeptides they optionally are substituted at R3 of substituents A1, A2 or A3 in Formula I. <br><br>
5 These conjugates are produced by forming an amide bond between a carboxyl group of the amino acid (or C-terminal amino acid of a polypeptide for example). Similarly, conjugates are formed between R3 (Formula 1) and an amino group of an amino acid or polypeptide. Generally, only one of any site in the parental molecule is amidated with an amino acid as described herein, 10 although it is within the scope of this invention to introduce amino acids at more than one permitted site, Usually, a carboxyl group of R3 is amidated with an amino acid. In general, the a-amino or a-carboxyl group of the amino acid or the terminal amino or carboxyl group of a polypeptide are bonded to the parental functionalities, i.e., carboxyl or amino groups in the amino acid side chains 15 generally are not used to form the amide bonds with the parental compound (although these groups may need to be protected during synthesis of the conjugates as described further below). <br><br>
With respect to the carboxyl-containing side chains of amino acids or polypeptides it will be understood that the carboxyl group optionally will be 20 blocked, e.g., by R1, esterified with R5 or amidated. Similarly, the amino side chains R16 optionally will be blocked with R1 or substituted with R5. <br><br>
Such ester or amide bonds with side chain amino or carboxyl groups, like the esters or amides with the parental molecule, optionally are hydrolyzable in vivo or in vitro under acidic (pH <3) or basic (pH >10) conditions, 25 Alternatively, they are substantially stable in the gastrointestinal tract of humans but are hydrolyzed enzymatically in blood or in intracellular environments. The esters or amino acid or polypeptide amidates also are useful as intermediates for the preparation of the parental molecule containing free amino or carboxyl groups. The free acid or base of the parental compound, for example, is readily 30 formed from the esters or amino acid or polypeptide conjugates of this invention by conventional hydrolysis procedures. <br><br>
When an amino acid residue contains one or more cliiral centers, any of the D, L, meso, threo or erythro (as appropriate) racemates, scalemates or <br><br>

WO 2004/096236 PCT/US2004/013143 <br><br>
mixtures thereof may be used. In general, if the intermediates are to be hydrolyzed non-enzymatically (as would be the case where the amides are used as chemical intermediates for the free acids or free amines), D isomers are useful. On the other hand, L isomers are more versatile since they can be 5 susceptible to both non-enzymatic and enzymatic hydrolysis, and are more efficiently transported by amino acid or dipeptidyl transport systems in the gastrointestinal tract. <br><br>

Polypeptides are polymers of amino acids in which a carboxyl group of one amino acid monomer is bonded to an amino or imino group of the next amino acid monomer by an amide bond. Polypeptides include dipeptides, low molecular weight polypeptides (about 1500-5000 MW) and proteins. Proteins 5 optionally contain 3, 5,10, 50, 75, 100 or more residues, and suitably are substantially sequence-homologous with human, animal, plant or microbial proteins. They include enzymes (e.g., hydrogen peroxidase) as well as immunogens such as KLH, or antibodies or proteins of any type against which one wishes to raise an immune response. The nature and identity of the 10 polypeptide may vary widely. <br><br>
The polypeptide amidates are useful as immunogens in raising antibodies against either the polypeptide (if it is not immunogenic in the animal to which it is administered) or against the epitopes on the remainder of the compound of this invention. <br><br>
15 Antibodies capable of binding to the parental non-peptidyl compound are used to separate the parental compound from mixtures, for example in diagnosis or manufacturing of the parental compound. The conjugates of parental compound and polypeptide generally are more immunogenic than the polypeptides in closely homologous animals, and therefore make the polypeptide 20 more immunogenic for facilitating raising antibodies against it. Accordingly, the polypeptide or protein may not need to be immunogenic in an animal typically used to raise antibodies, e.g., rabbit, mouse, horse, or rat, but the final product conjugate should be immunogenic in at least one of such animals. The polypeptide optionally contains a peptidolytic enzyme cleavage site at the 25 peptide bond between the first and second residues adjacent to the acidic heteroatom. Such cleavage sites are flanked by enzymatic recognition structures, e.g., a particular sequence of residues recognized by a peptidolytic enzyme. <br><br>
Peptidolytic enzymes for cleaving the polypeptide conjugates of this 30 invention are well known, and in particular include carboxypeptidases. <br><br>
Carboxypeptidases digest polypeptides by removing C-terminal residues, and are specific in many instances for particular C-terminal sequences. Such enzymes and their substrate requirements in general are well known. For example, a <br><br>

dipeptide (having a given pair of residues and a free carboxyl terminus) is covalently bonded through its a-amino group to the phosphorus or carbon atoms of the compounds herein. In claims where W} is phosphonate it is expected that this peptide will be cleaved by the appropriate peptidolytic enzyme, leaving the 5 carboxyl of the proximal amino acid residue to autocatalytically cleave the phosphonoamidate bond. <br><br>

Tripeptide Residues are also useful as protecting groups. When a phosphonate is to be protected, the sequence -X4-pro-X5- (where X4 is any amino <br><br>

acid residue and X5 is an amino acid residue, a carboxyl ester of proline, or hydrogen) will be cleaved by luminal carboxypeptidase to yield X4 with a free carboxyl, which in turn is expected to autocatalytically cleave the phosphonoamidate bond. The carboxy group of x5 optionally is esterified with 5 benzyl. <br><br>
Dipeptide or tripeptide species can be selected on the basis of known transport properties and/or susceptibility to peptidases that can affect transport to intestinal mucosal or other cell types. Dipeptides and tripeptides lacking an a-amino group are transport substrates for the peptide transporter found in brush 10 border membrane of intestinal mucosal cells (Bai, J.P.F., (1992) Pharm Res. 9:969-978). Transport competent peptides can thus be used to enhance bioavailability of the amidate compounds. Di- or tripeptides having one or more amino acids in the D configuration are also compatible with peptide transport and can be utilized in the amidate compounds of this invention. Amino acids in 15 the D configuration can be used to reduce the susceptibility of a di- or tripeptide to hydrolysis by proteases common to the brush border such as aminopeptidase N. In addition, di- or tripeptides alternatively are selected on the basis of their relative resistance to hydrolysis by proteases found in the lumen of the intestine. For example, tripeptides or polypeptides lacking asp and/or glu are poor 20 substrates for aminopeptidase A, di- or tripeptides lacking amino acid residues on the N-terminal side of hydrophobic amino acids (leu, tyr, phe, val, trp) are poor substrates for endopeptidase, and peptides lacking a pro residue at the penultimate position at a free carboxyl terminus are poor substrates for carboxypeptidase P. Similar considerations can also be applied to the selection 25 of peptides that are either relatively resistant or relatively susceptible to hydrolysis by cytosolic, renal, hepatic, serum or other peptidases. Such poorly cleaved polypeptide amidates are immunogens or are useful for bonding to proteins in order to prepare immunogens. <br><br>

Selected substituents within the compounds of the invention are present to a recursive degree. In this context, "recursive substituent" means that a substituent may recite another instance of itself. Because of the recursive nature of such substituents, theoretically, a large number maybe present in any given 25 claim. For example, Rx contains a Ry substituent. Ry can be R2, which in turn can be R3. If R3 is selected to be R3c, then a second instance of Rx can be selected. One of ordinary skill in the art of medicinal chemistry understands that the total number of such substituents is reasonably limited by the desired properties of the compound intended. Such properties include, by of example 30 and not limitation, physical properties such as molecular weight, solubility or log P, application properties such as activity against the intended target, and practical properties such as ease of synthesis. <br><br>

More typically, each of these may independently occur 12 or fewer 5 times in a given claim. More typically yet, W3 will occur 0 to 8 times, Ky will occur 0 to 6 times and R3 will occur 0 to 10 times in a given claim. Even more typically, W3 will occur 0 to 6 times, Ry will occur 0 to 4 times and R3 will occur 0 to 8 times in a given claim. <br><br>
Recursive substituents are an intended aspect of the invention. One of 10 ordinary skill in the art of medicinal chemistry understands the versatility of such substituents. To the degree that recursive substituents are present in an claim of the invention, the total number will be determined as set forth above. <br><br>

Intracellular Targeting <br><br>
The phosphonate group of the compounds of the invention may cleave in vivo in stages after they have reached the desired site of action, i.e. inside a cell. One mechanism of action inside a cell may entail a first cleavage, e.g. by 15 esterase, to provide a negatively-charged "loeked-in" intermediate. Cleavage of a terminal ester grouping in a compound of the invention thus affords an unstable intennediate which releases a negatively charged "locked in" intermediate. <br><br>
After passage inside a cell, intracellular enzymatic cleavage or 20 modification of the phosphonate or prodrug compound may result in an intracellular accumulation of the cleaved or modified compound by a "trapping" mechanism. The cleaved or modified compound may then be "locked-in" the cell by a significant change in charge, polarity, or other physical property change which decreases the rate at which the cleaved or modified compound can exit the 25 cell, relative to the rate at which it entered as the phosphonate prodrug. Other mechanisms by which a therapeutic effect are achieved may be operative as well. Enzymes which are capable of an enzymatic activation mechanism with the phosphonate prodrug compounds of the invention include, but are not limited to, amidases, esterases, microbial enzymes, phospholipases, cholinesterases, and 30 phosphatases. <br><br>

Both racemic and diastereomeric mixtures, as well as the individual optical isomers isolated or synthesized, substantially free of their enantiomeric or diastereomeric partners, are all within the scope of the invention. The racemic mixtures are separated into their individual, substantially optically 25 pure isomers through well-known techniques such as, for example, the separation of diastereomeric salts formed with optically active adjuncts, e.g., <br><br>
acids or bases followed by conversion back to the optically active substances. In most instances, the desired optical isomer is synthesized by means of stereospccific reactions, beginning with the appropriate stereoisomer of the 30 desired starting material. <br><br>
The compounds of the invention can also exist as tautomeric isomers in certain cases. All though only one delocalized resonance structure may be depicted, all such forms are contemplated within the scope of the invention. For <br><br>

invention. <br><br>
Compositions of the invention may act as inhibitors of immune-modulation, as intermediates for such inhibitors or have other utilities as described below. The inhibitors will bind to locations on the surface or in a cavity of an immuno-modulator having a geometry unique to immuno-modulators. Compositions binding immuno-modulators may bind with varying degrees of reversibility. Those compounds binding substantially irreversibly are ideal candidates for use in this method. Once labeled, the substantially irreversibly binding compositions are useful as probes for the detection of immune-modulation. Accordingly, herein described are methods of detecting immune-modulation in a sample suspected of containing an immuno-modulator comprising the steps of: treating a sample suspected of containing an immuno-modulator with a composition comprising a compound of the invention bound to a label; and observing the effect of the sample on the activity of the label. Suitable labels are well known in the diagnostics field and include stable free radicals, fluorophores, radioisotopes, enzymes, chemiluminescent groups and chromogens. The compounds herein are labeled in conventional fashion using functional groups such as hydroxyl or amino. <br><br>
Within the context of the invention samples suspected of containing an immuno-modulator include natural or man-made materials such as living organisms; tissue or cell cultures; biological samples such as biological material samples (blood, serum, urine, cerebrospinal fluid, tears, sputum, saliva, tissue samples, and the like); laboratory samples; food, water, or air samples; bioproduct samples such as extracts of cells, particularly recombinant cells synthesizing a desired glycoprotein; and the like. Typically the sample will be suspected of containing an immuno-modulator. Samples can be contained in any medium including water and organic solvent/water mixtures. Samples include living organisms such as humans, and man made materials such as cell cultures. <br><br>
The treating step comprises adding the composition of the invention to the sample or it comprises adding a precursor of the composition to the sample. The addition step comprises any method of administration as described above. <br><br>

composition, can be observed by any method including direct and indirect methods of detecting immuno-modulator activity. Quantitative, qualitative, and semiquantitative methods of determining immuno-modulation activity are all contemplated. Typically one of the screening methods described above are 5 applied, however, any other method such as observation of the physiological properties of a living organism are also applicable. <br><br>
However, in screening compounds capable of inhibiting immuno-modulation it should be kept in mind that the results of enzyme assays may not correlate with cell culture assays. Thus, a cell based assay should be the primary 10 screening tool. <br><br>
Screens for Immuno-Modulating Inhibitors <br><br>
Compositions of the invention are screened for inhibitory activity against immuno-modulators by any of the conventional techniques for evaluating enzyme activity. Within the context of the invention, typically compositions are 15 first screened for inhibition of immuno-modulators in vitro and compositions showing inhibitory activity are then screened for activity in vivo. Compositions having in vitro Ki (inhibitory constants) of less then about 5 X 10~6 M, typically less than about 1 X 10~7 M and preferably less than about 5 X 10"^ M are preferred for in vivo use. <br><br>
20 Useful in vitro screens have been described in detail and will not be elaborated here. However, the examples describe suitable in vitro assays. <br><br>
Pharmaceutical Formulations <br><br>
The compounds of this invention are formulated with conventional carriers and excipients, which will be selected in accord with ordinary practice. 25 Tablets will contain excipients, glidants, fillers, binders and the like.

The invention further provides veterinary compositions comprising at 15 least one active ingredient as above defined together with a veterinary carrier therefor. <br><br>
Veterinary carriers are materials useful for the purpose of administering the composition and may be solid, liquid or gaseous materials which are otherwise inert or acceptable in the veterinary art and are compatible with the 20 active ingredient. These veterinary compositions maybe administered orally, parenterally or by any other desired route. <br><br>
Compounds of the invention can also be formulated to provide controlled release of the active ingredient to allow less frequent dosing or to improve the pharmacokinetic or toxicity profile of the active ingredient. Accordingly, the 25 invention also provided compositions comprising one or more compounds of the invention formulated for sustained or controlled release. <br><br>
Effective dose of active ingredient depends at least on the nature of the condition being treated, toxicity, whether the compound is being used prophylactically (lower doses) or against an active infection, the method of 30 delivery, and the pharmaceutical formulation, and will be determined by the clinician using conventional dose escalation studies. It can be expected to be from about 0.0001 to about 100 mg/kg body v/eight per day. Typically, from about 0.01 to about 10 mg/kg body weight per day. More typically, from about <br><br>

WO 2004/096236 PCT/US2004/013143 <br><br>
.01 to about 5 mg/kg body weight per day. More typically, from about .05 to about 0.5 mg/kg body weight per day. For example, the daily candidate dose for an adult human of approximately 70 kg body weight will range from 1 mg to 1000 mg, preferably between 5 mg and 500 mg, and may take the form of single 5 or multiple doses. <br><br>
Routes of Administration <br><br>
One or more compounds of the invention (herein referred to as the active ingredients) are administered by any route appropriate to the condition to be treated. Suitable routes include oral, rectal, nasal, topical (including buccal and 10 sublingual), vaginal and parenteral (including subcutaneous, intramuscular, intravenous, intradermal, intrathecal and epidural), and the like. It will be appreciated that the preferred route may vary with for example the condition of the recipient. An advantage of the compounds of this invention is that they are orally bioavailable and can be dosed orally. <br><br>
15 Combination Therapy <br><br>
Active ingredients of the invention are also used in combination with other active ingredients. Such combinations are selected based on the condition to be treated, cross-reactivities of ingredients and pharmaco-properties of the combination. <br><br>
20 It is also possible to combine any compound of the invention with one or more other active ingredients in a unitary dosage fonn for simultaneous or sequential administration to a patient. The combination therapy may be administered as a simultaneous or sequential regimen. When administered sequentially, the combination may be administered in two or more 25 administrations. <br><br>
The combination therapy may provide "synergy" and "synergistic effect", i.e. the effect achieved when the active ingredients used together is greater than the sum of the effects that results from using the compounds separately. A synergistic effect may be attained when the active ingredients are: (1) co-30 formulated and administered or delivered simultaneously in a combined formulation; (2) delivered by alternation or in parallel as separate formulations; or (3) by some other regimen. When delivered in alternation therapy, a <br><br>
-110- <br><br>
542343 <br><br>
WO 2004/096236 PCT/US2004/013143 <br><br>
synergistic effect may be attained when the compounds are administered or delivered sequentially, e.g., in separate tablets, pills or capsules, or by different injections in separate syringes. In general, during alternation therapy, an effective dosage of each active ingredient is administered sequentially, i.e. <br><br>
5 serially, whereas in combination therapy, effective dosages of two or more active ingredients are administered together. <br><br>
Metabolites of the Compounds of the Invention <br><br>
Also falling within the scope of this invention are the in vivo metabolic products of the compounds described herein. Such products may result for 10 example from the oxidation, reduction, hydrolysis, amidation, esterification and the like of the administered compound, primarily due to enzymatic processes. Accordingly, the invention includes compounds produced by a process comprising contacting a compound of this invention with a mammal for a period of time sufficient to yield a metabolic product thereof. Such products typically 15 are identified by preparing a radiolabelled (e.g., C^ or H^) compound of the invention, administering it parenterally in a detectable dose (e.g., greater than about 0.5 mg/kg) to an animal such as rat, mouse, guinea pig, monkey, or to man, allowing sufficient time for metabolism to occur (typically about 30 seconds to 30 hours) and isolating its conversion products from the urine, blood 20 or other biological samples. These products are easily isolated since they are labeled (others are isolated by the use of antibodies capable of binding epitopes surviving in the metabolite). The metabolite structures are determined in conventional fashion, e.g., by MS or NMR analysis. In general, analysis of metabolites is done in the same way as conventional drug metabolism studies 25 well-known to those skilled in the art. The conversion products, so long as they are not otherwise found in vivo, are useful in diagnostic assays for therapeutic dosing of the compounds of the invention even if they possess no immuno-modulation inhibitory activity of their own. <br><br>
Recipes and methods for determining stability of compounds in surrogate 30 gastrointestinal secretions are known. Compounds are defined herein as stable in the gastrointestinal tract where less than about 50 mole percent of the protected groups are deprotected in surrogate intestinal or gastric juice upon <br><br>
- Ill - <br><br>
542343 <br><br>
incubation for 1 hour at 37 °C. Simply because the compounds are stable to the gastrointestinal tract does not mean that they cannot be hydrolyzed in vivo. The phosphonate prodrugs of the invention typically will be stable in the digestive system but are substantially hydrolyzed to the parental drug in the digestive lumen, liver or other metabolic organ, or within cells in general. <br><br>
Exemplary Methods of Making the Compounds of the Invention. <br><br>
Also described are methods of making the compositions of the invention. The compositions are prepared by any of the applicable techniques of organic synthesis. Many such techniques are well known in the art. However, many of the known techniques are elaborated in Compendium of Organic Synthetic Methods (John Wiley & Sons, New York), Vol. 1, Ian T. Harrison and Shuyen Harrison, 1971; Vol. 2, Ian T. Harrison and Shuyen Harrison, 1974; Vol. 3, <br><br>

A number of exemplary methods for the preparation of the compositions of the invention are provided below. These methods are intended to illustrate the nature of such preparations are not intended to limit the scope of applicable methods. <br><br>
Generally, the reaction conditions such as temperature, reaction time, solvents, work-up procedures, and the like, will be those common in the art for the particular reaction to be performed. The cited reference material, together with material cited therein, contains detailed descriptions of such conditions. Typically the temperatures will be -100°C to 200°C, solvents will be aprotic or protic, and reaction times will be 10 seconds to 10 days. Work-up typically consists of quenching any unreacted reagents followed by partition between a water/organic layer system (extraction) and separating the layer containing the product. <br><br>
Oxidation and reduction reactions are typically carried out at temperatures near room temperature (about 20 °C), although for metal hydride <br><br>

reductions frequently the temperature is reduced to 0 °C to -100 °C, solvents are typically aprotic for reductions and may be either protic or aprotic for oxidations. Reaction times are adjusted to achieve desired conversions. <br><br>
Condensation reactions are typically carried out at temperatures near 5 room temperature, although for non-equilibrating, kinetically controlled condensations reduced temperatures (0 °C to -100 °C) are also common. <br><br>
Solvents can be either protic (common in equilibrating reactions) or aprotic (common in kinetically controlled reactions). <br><br>
Standard synthetic techniques such as azco tropic removal of reaction by-10 products and use of anhydrous reaction conditions (e.g., inert gas environments) are common in the art and will be applied when applicable. <br><br>
Schemes and Examples <br><br>
General aspects of these exemplary methods are described below and in the Examples. Each of the products of the following processes is optionally 15 separated, isolated, and/or purified prior to its use in subsequent processes. <br><br>

Standard synthetic techniques such as azeotropic removal of reaction byproducts and use of anhydrous reaction conditions (e.g., inert gas environments) are common in the art and will be applied when applicable. <br><br>
5 The terms "treated" "treating", "treatment", and the like, when used in connection with a chemical synthetic operation, mean contacting, mixing, <br><br>
reacting, allowing to react, bringing into contact, and other terms common in the art for indicating that one or more chemical entities is treated in such a manner as to convert it to one or more other chemical entities. This means that "treating 10 compound one with compound two" is synonymous with "allowing compound one to react with compound two", "contacting compound one with compound two", "reacting compound one with compound two", and other expressions common in the art of organic synthesis for reasonably indicating that compound one was "treated", "reacted", "allowed to react", etc., with compound two. For 15 example, treating indicates the reasonable and usual manner in which organic chemicals are allowed to react. Normal concentrations (0.01M to 10M, typically 0.1M to 1M), temperatures (-100 °C to 250 °C, typically -78 °C to 150 °C, more typically -78 °C to 100 °C, still more typically 0 °C to 100 °C), reaction vessels (typically glass, plastic, metal), solvents, pressures, atmospheres (typically air 20 for oxygen and water insensitive reactions or nitrogen or argon for oxygen or water sensitive), etc., are intended unless otherwise indicated. The knowledge of similar reactions known in the art of organic synthesis are used in selecting the conditions and apparatus for "treating" in a given process. In particular, one of ordinary skill in the art of organic synthesis selects conditions and apparatus 25 reasonably expected to successfully carry out the chemical reactions of the described processes based on the knowledge in the art. <br><br>
Modifications of each of the exemplary schemes and in the examples (hereafter "exemplary schemes") leads to various analogs of the specific exemplary materials produce. The above-cited citations describing suitable 30 methods of organic synthesis are applicable to such modifications. <br><br>
In each of the exemplary schemes it may be advantageous to separate reaction products from one another and/or from starting materials. The desired products of each step or series of steps is separated and/or purified (hereinafter <br><br>

WO 2004/096236 PCT/US2004/013143 <br><br>
i separated) to the desired degree of homogeneity by the techniques common in the art. Typically such separations involve multiphase extraction, crystallization from a solvent or solvent mixture, distillation, sublimation, or chromatography. Chromatography can involve any number of methods including, for example: 5 reverse-phase and normal phase; size exclusion; ion exchange; high, medium, and low pressure liquid chromatography methods and apparatus; small scale analytical; simulated moving bed (8MB) and preparative thin or thick layer chromatography, as well as techniques of small scale thin layer and flash chromato graphy. <br><br>
10 Mother class of separation methods involves treatment of a mixture with a reagent selected to bind to or render otherwise separable a desired product, unreacted starting material, reaction by product, or the like. Such reagents include adsorbents or absorbents such as activated carbon, molecular sieves, ion exchange media, or the like. Alternatively, the reagents can be acids in the case 15 of a basic material, bases in the case of an acidic material, binding reagents such as antibodies, binding proteins, selective chelators such as crown ethers, liquid/liquid ion extraction reagents (LIX), or the like. <br><br>
Selection of appropriate methods of separation depends on the nature of the materials involved. For example, boiling point, and molecular weight in 20 distillation and sublimation, presence or absence of polar functional groups in chromatography, stability of materials in acidic and basic media in multiphase extraction, and the like. One skilled in the art will apply techniques most likely to achieve the desired separation. <br><br>
A single stereoisomer, e.g., an enantiomer, substantially free of its 25 stereoisomer may be obtained by resolution of the racemic mixture using a method such as formation of diastereomers using optically active resolving agents (Stereochemistry of Carbon Compounds, (1962) by E. L. Eliel, McGraw Hill; Lochmuller, C. H., (1975) J. Chromatogr., 113:(3) 283-302). Racemic mixtures of chiral compounds of the invention can be separated and isolated by 30 any suitable method, including: (1) formation of ionic, diastereomeric salts with chiral compounds and separation by fractional crystallization or other methods, (2) formation of diastereomeric compounds with chiral derivatizing reagents, separation of the diastereomers, and conversion to the pure stereoisomers, and <br><br>

542343 <br><br>
WO 2004/096236 PCT/US2004/013143 <br><br>
(3) separation of the substantially pure or enriched stereoisomers directly under chiral conditions. <br><br>
I <br><br>
Under method (1), diastereomeric salts can be formed by reaction of enantiomerically pure chiral bases such as brucine, quinine, ephedrine, 5 strychnine, a-methyl-p-phenylethylamine (amphetamine), and the like with asymmetric compounds bearing acidic functionality, such as carboxylic acid and sulfonic acid. The diastereomeric salts maybe induced to separate by fractional crystallization or ionic chromatography. For separation of the optical isomers of amino compounds, addition of chiral carboxylic or sulfonic acids, such as 10 camphorsulfonic acid, tartaric acid, mandelic acid, or lactic acid can result in formation of the diastereomeric salts. <br><br>
Alternatively, by method (2), the substrate to be resolved is reacted with one enantiomer of a chiral compound to form a diastereomeric pair (Eliel, E. and Wilen, S. (1994) Stereochemistry of Organic Compounds. John Wiley & Sons, 15 Inc., p. 322). Diastereomeric compounds can be formed by reacting asymmetric compounds with enantiomerically pure chiral derivatizing reagents, such as menthyl derivatives, followed by separation of the diastereomers and hydrolysis to yield the free, enantiomerically enriched xanthene. A method of determining optical purity involves making chiral esters, such as a menthyl ester, e.g., (-) 20 menthyl chloro formate in the presence of base, or Mosher ester, a-methoxy-a-(trifluoromethyl)phenyl acetate (Jacob III. (1982) J. Org. Chem. 47:4165), of the t <br><br>
racemic mixture, and analyzing the NMR spectrum for the presence of the two atropisomeric diastereomers. Stable diastereomers of atropisomeric compounds can be separated and isolated by normal- and reverse-phase chromatography 25 following methods for separation of atropisomeric naphthyl-isoquinolines (Hoye, T., WO 96/15111). By method (3), a racemic mixture of two enantiomers can be separated by chromatography using a chiral stationary phase (Chiral Liquid Chromatography (1989) W. J. Lough, Ed. Chapman and Hall, New York; Okamoto, (1990) J. of Chromalogr. 513:375-378). Enriched or 30 purified enantiomers can be distinguished by methods used to distinguish other chiral molecules with asymmetric carbon atoms, such as optical rotation and circular dichroism. <br><br>

Examples General Section <br><br>
A number of exemplary methods for the preparation of compounds of the invention are provided herein, for example, in the Examples hereinbelow.. <br><br>
These methods are intended to illustrate the nature of such preparations are not 5 intended to limit the scope of applicable methods. Certain compounds of the invention can be used as intermediates for the preparation of other compounds of the invention. For example, the interconversion of various phosphonate compounds of the invention is illustrated below. <br><br>
10 1XTERCONV"ERSIONS OF THE PHOSPHONATES R-LINK-PCOVOR1^. R-L1NK-P( OK OR1 ¥QH) AND R-LINK-P(0¥0HK <br><br>
The following schemes 32-38 described the preparation of phosphonate esters of the general structure R-link-PfOXOR1^, in which the groups R1 may be the same or different. The R1 groups attached to a phosphonate ester, or to 15 precursors thereto, may be changed using established chemical transformations. The interconversion reactions of phosphonates are illustrated in Scheme S32. The group R in Scheme 32 represents the substructure, i.e. the drug "scaffold, to which the substituent link-P(0)(OR1)2 is attached, either in the compounds of the invention, or in precursors thereto. At the point in the synthetic route of 20 conducting a phosphonate interconversion, certain functional groups in R may be protected. The methods employed for a given phosphonate transformation depend on the nature of the substituent R1, and of the substrate to which the phosphonate group is attached. The preparation and hydrolysis of phosphonate esters is described in Organic Phosphorus Compounds. G. M. Kosolapoff. L. 25 Maeir, eds, Wiley, 1976, p. 9ff. <br><br>
hi general, synthesis of phosphonate esters is achieved by coupling a nucleophile amine or alcohol with the corresponding activated phosphonate electrophilic precursor. For example, chlorophosphonate addition on to 5'-hydroxy of nucleoside is a well known method for preparation of nucleoside 30 phosphate monoesters. The activated precursor can be prepared by several well known methods. Chlorophosphonates useful for synthesis of the prodrugs are prepared from the substituted-1,3-propanediol (Wissner, et al, (1992) J. Med Chem. 35:1650). Chlorophosphonates are made by oxidation of the <br><br>

542343 <br><br>
WO 2004/096236 PCT/US2004/013143 <br><br>
corresponding chlorophospholanes (Anderson, et al, (1984) J. Org. Chem. 49:1304) which are obtained by reaction of the substituted diol with phosphorus trichloride. Alternatively, the chlorophosphonate agent is made by treating substituted-1,3-diols with phosphorusoxychloride (Patois, et al, (1990) J. Chem. <br><br>
5 Soc. Perkin Trans. /, 1577). Chlorophosphonate species may also be generated in situ from corresponding cyclic phosphites (Silverburg, et al., (1996) Tetrahedron lett., 37:771-774), which in turn can be either made from chlorophospholane or phosphoramidate intermediate. Phosphoroflouridate intermediate prepared either from pyrophosphate or phosphoric acid may also act as precursor in preparation 10 of cyclic prodrugs (Watanabe et al., (1988) Tetrahedron lett., 29:5763-66). <br><br>
Phosphonate prodrugs of the present invention may also be prepared from the free acid by Mitsunobu reactions (Mitsunobu, (1981) Synthesis, 1; Campbell, (1992) J. Org. Chem. 57:6331), and other acid coupling reagents including, but not limited to, carbodiimides (Alexander, et al, (1994) Collect. 15 Czech. Chem. Commun. 59:1853; Casara et al, (1992) Bioorg. Med. Chem. Lett. 2:145; Ohashi et al, (1988) Tetrahedron Lett., 29:1189), and benzotriazolyloxytris-(dimethylamino)phosphonium salts (Campagne et al (1993) Tetrahedron Lett. 34:6743). <br><br>
Aryl halides undergo Ni+2 catalyzed reaction with phosphite derivatives 20 to give aryl phosphonate containing compounds (Balthazar, et al (1980) J. Org. Chem. 45:5425). Phosphonates may also be prepared from the chlorophosphonate in the presence of a palladium catalyst using aromatic triflates (Petrakis et al (1987) J. Am. Chem. Soc. 109:2831; Lu et al (1987) Synthesis 726). In another method, aryl phosphonate esters are prepared from 25 aryl phosphates under anionic rearrangement conditions (Melvin (1981) <br><br>
Tetrahedron Lett. 22:3375; Casteel et al (1991) Synthesis, 691). N-Alkoxy aryl salts with alkali met al derivatives of cyclic alkyl phosphonate provide general synthesis for heteroaryl-2-phosphonate linkers (Redmore (1970) J. Org. Chem. 35:4114). These above mentioned methods can also be extended to compounds 30 where the W5 group is a heterocycle. Cyclic-l,3-propanyl prodrugs of phosphonates are also synthesized from phosphonic diacids and substituted propane-l,3-diols using a coupling reagent such as 1,3-dicyclohexylcarbodiimide (DCC) in presence of a base (e.g., pyridine). Other <br><br>

carbodiimide based coupling agents like 1,3-disopropylcarbodiimide or water soluble reagent, l-(3-dimethylaminopropyl)-3-ethylcarbodiimide hydrochloride (EDCI) can also be utilized for the synthesis of cyclic phosphonate prodrugs. <br><br>
The conversion of a phosphonate diester S32.1 into the corresponding 5 phosphonate monoester §32.2 (Scheme 32, Reaction 1) is accomplished by a number of methods. For example, the ester S32.1 in which R1 is an aralkyl group such as benzyl, is converted into the monoester compound S32.2 by reaction with a tertiary organic base such as diazabicyclooctane (DABCO) or quinuclidine, as described in J Org. Chem. (1995) 60:2946. The reaction is 10 performed in an inert hydrocarbon solvent such as toluene or xylene, at about 110 °C. The conversion of the diester S32.1 in which R1 is an aryl group such as phenyl, or an alkenyl group such as allyl, into the monoester S32.2 is effected by treatment of the ester S32.1 with a base such as aqueous sodium hydroxide in acetonitrile or lithium hydroxide in aqueous tetrahydrofuran. Phosphonate 15 , diesters S32.1 in which one of the groups R1 is aralkyl, such as benzyl, and the other is alkyl, is converted into the monoesters S32.2 in which R1 is alkyl by hydrogenation, for example using a palladium on carbon catalyst. Phosphonate diesters in which both of the groups R1 are alkenyl, such as allyl, is converted into the monoester S32.2 in which R1 is alkenyl, by treatment with 20 chlorotris(triphenylphosphine)rhodium (Wilkinson's catalyst) in aqueous ethanol at reflux, optionally in the presence of diazabicyclooctane, for example by using the procedure described in J. Org. Chem. (1973) 38:3224, for the cleavage of allyl carboxylates. <br><br>
The conversion of a phosphonate diester S32.1 or a phosphonate 25 monoester S32.2 into the corresponding phosphonic acid S32.3 (Scheme 32, Reactions 2 and 3) can be effected by reaction of the diester or the monoester with trimethylsilyl bromide, as described in J. Chem. Soc., Chem. Comm., (1979) 739. The reaction is conducted in an inert solvent such as, for example, dichloromethane, optionally in the presence of a silylating agent such as 30 bis(trimethylsilyl)triiluoroacetamide, at ambient temperature. A phosphonate monoester S32.2 in which R1 is aralkyl such as benzyl, is converted into the corresponding phosphonic acid S32.3 by hydrogenation over a palladium catalyst, or by treatment with hydrogen chloride in an ethereal solvent such as <br><br>

WO 2004/096236 PCT/US2004/013143 <br><br>
dioxane. A phosphonate monoester S32.2 in which R1 is alkenyl such as, for example, allyl, is converted into the phosphonic acid S32.3 by reaction with Wilkinson's catalyst in an aqueous organic solvent, for example in 15% aqueous acetonitrile, or in aqueous ethanol, for example using the procedure described in 5 Helv. Chim. Acta. (1985) 68:618. Palladium catalyzed hydrogenolysis of phosphonate esters S32.1 in which Rl is benzyl is described in J. Org. Chem. (1959) 24:434. Platinum-catalyzed hydrogenolysis of phosphonate esters S32.1 in which R1 is phenyl is described in J. Am. Chem. Soc. (1956) 78:2336. <br><br>
The conversion of a phosphonate monoester S32.2 into a phosphonate 10 diester S32.1 (Scheme 32, Reaction 4) in which the newly introduced R1 group is alkyl, aralkyl, haloalkyl such as chloro ethyl, or aralkyl is effected by a number of reactions in which the substrate S32.2 is reacted with a hydroxy compound R! OH, in the presence of a coupling agent. Typically, the second phosphonate ester group is different than the first introduced phosphonate ester group, i.e. R1 15 is followed by tlie introduction of R2 where each of R1 and R2 is alkyl, aralkyl, haloalkyl such as chloroethyl, or aralkyl (Scheme 32, Reaction 4a) whereby S32.2 is converted to S32.1a. Suitable coupling agents are those employed for the preparation of carboxylate esters, and include a carbodiimide such as dicyclohexylcarbodiimide, in which case the reaction is preferably conducted hi 20 a basic organic solvent such as pyridine, or (benzotriazol-1- <br><br>
yloxy)tripyrrolidinophosphonium hexafluorophosphate (PYBOP, Sigma), in which case the reaction is performed in a polar solvent such as dimethylformamide, in the presence of a tertiary organic base such as diisopropylethylamine, or Aldrithiol-2 (Aldrich) in which case the reaction is 25 conducted in a basic solvent such as pyridine, in the presence of a triaryl phosphine such as triphenylphosphine. Alternatively, the conversion of the phosphonate monoester S32.2 to the diester S32.1 is effected by the use of the Mitsunobu reaction, as described above. The substrate is reacted with the hydroxy compound R'OH, in the presence of diethyl azodicarboxylate and a 30 triarylphosphine such as triphenyl phosphine. Alternatively, the phosphonate monoester S32.2 is transformed into the phosphonate diester S32.1, in which the introduced R1 group is alkenyl or aralkyl, by reaction of the monoester with the halide R^r, in which R1 is as alkenyl or aralkyl. The alkylation reaction is <br><br>

conducted in a polar organic solvent such as dimethylformamide or acetonitrile, in the presence of a base such as cesium carbonate. Alternatively, the phosphonate monoester is transformed into the phosphonate diester in a two step procedure. In the first step, the phosphonate monoester s32.2 is transformed into 5 the chloro analog RPCOXOR^Cl. by reaction with thionyl chloride or oxalyl chloride and the like, as described in Organic Phosphorus Compounds, G. M. Kosolapoff, L. Maeir, eds, Wiley, 1976, p. 17, and the thus-obtained product RP(0)(0R')C1 is then reacted with the hydroxy compound R'OH, in the presence of a base such as triethylamine, to afford the phosphonate diester s32.1. 10 A phosphonic acid R-link-P(0)(0H)2 is transformed into a phosphonate monoester RP(0)(0R1)(0H) (Scheme 32, Reaction 5) by means of the methods described above of for the preparation of the phosphonate diester R-link- <br><br>

phosphonic acids S32.3 are transformed into phosphonic esters S32.1 in which R1 is aryl, by means of a coupling reaction employing, for example, dicyclohexylcarbodiimide in pyridine at ca 70 °C. Alternatively, phosphonic 25 acids S32.3 are transformed into phosphonic esters S32.1 in which R1 is alkenyl, by means of an alkylation reaction.

Preparation of phosphonate carbamates. <br><br>
Phosphonate esters may contain a carbamate linkage. The preparation of 5 carbamates is described in Comprehensive Organic Functional Group <br><br>
Transformations, A. R. Katritzlcy, ed., Pergamon, 1995, Vol. 6, p, 416ff, and in Organic Functional Group Preparations, by S. R. Sandler and W. Karo, Academic Press, 1986, p. 260ff, The carbamoyl group may be formed by reaction of a hydroxy group according to the methods known in the art, 10 including the teachings of Ellis, US 2002/0103378 Al and Hajima, US 6018049. <br><br>

The latter 10 compound is then reacted with the amine component S33.3, in the presence of an organic or inorganic base, to afford the carbamate S33.7. For example, the chloroformyl compound S33.6 is reacted with the amine S33.3 in a water-miscible solvent such as tetrahydrofiiran, in the presence of aqueous sodium hydroxide, as described in Org. Svn. Coll. Vol. 3. 167, 1965, to yield the 15 carbamate S33.7. Alternatively, the reaction is performed in dichloromethane in the presence of an organic base such as diisopropylethylamine or dimethylaminopyridine. <br><br>
Scheme 33, Example 2 depicts the reaction of the chloroformate compound S33.6 with imidazole to produce the imidazolide S33.8. The 20 imidazolide product is then reacted with the amine S33.3 to yield the carbamate S33.7. The preparation of the imidazolide is performed in an aprotic solvent such as dichloromethane at 0°, and the preparation of the carbamate is conducted in a similar solvent at ambient temperature, optionally in the presence of a base such as dimethylaminopyridine, as described in J.Med. Chem., 1989, 32, 357. 25 Scheme 33 Example 3, depicts the reaction of the chloroformate S33.6 <br><br>
with an activated hydroxyl compound R"OH, to yield the mixed carbonate ester S33.10, The reaction is conducted in an inert organic solvent such as ether or dichloromethane, in the presence of a base such as dicyclohexylamine or triethylamine. The hydroxyl component R"OH is selected from the group of 30 compounds S33.19 - S33.24 shown in Scheme 33, and similar compounds. For example, if the component R"OH is hydroxybenztriazole S33.19, N-hydroxysuccmimide S33.20, or pentachlorophenol, S33.21, the mixed carbonate S33.10 is obtained by the reaction of the chloroformate with the hydroxyl <br><br>

PREPARATION OF CARBOALKOXY-SUBSTITUTED PHOSPHONATE BISAMIDATES. MONOAMIDATES. DIESTERS AND MONQESTERS. 5 A number of methods are available for the conversion of phosphonic acids Into amidates and esters. In one group of methods, the phosphonic acid is either converted into an isolated activated intermediate such as a phosphoryl <br><br>

chloride, or the phosphonic acid is activated in situ for reaction with an amine or a hydroxy compound. <br><br>
The conversion of phosphonic acids into phosphoryl chlorides is accomplished by reaction with thionyl chloride, for example as described in J. 5 Gen. Chem. USSR, 1983, 53,480, Zh. Ohschei Khim., 1958, 28, 1063, or J. Org. Chem., 1994, 59, 6144, or by reaction with oxalyl chloride, as described in J. Am. Chem. Soc., 1994,116, 3251, or J. Org. Chem., 1994, 59, 6144, or by reaction with phosphorus pentachloride, as described in J. Org. Chem., 2001, 66, 329, or in J. Med, Chem., 1995, 38,1372. The resultant phosphoryl chlorides are 10 then reacted with amines or hydroxy compounds in the presence of a base to afford the amidate or ester products. <br><br>
Phosphonic acids are converted into activated imidazolyl derivatives by reaction with carbonyl diimidazole, as described in J. Chem. Soc., Chem. Comm. (1991) 312, ox Nucleosides &Nucleotides (2000) 19:1885. Activated 15 sulfonyloxy derivatives are obtained by the reaction of phosphonic acids with trichloromethylsulfonyl chloride or with triisopropylbenzenesulfonyl chloride, as described in Tet. Lett. (1996) 7857, ox Bioorg. Med. Chem. Lett. (1998) 8:663. The activated sulfonyloxy derivatives are then reacted with amines or hydroxy compounds to afford amidates or esters. <br><br>
20 Alternatively, the phosphonic acid and the amine or hydroxy reactant are combined in the presence of a diimide coupling agent. The preparation of phosphonic amidates and esters by means of coupling reactions in the presence of dicyclohexyl carbodiimide is described, for example, in J. Chem. Soc., Chem. Comm. (1991) 312 or Coll. Czech. Chem. Comm. (1987) 52:2792. The use of 25 ethyl dimethylaminopropyl carbodiimide for activation and coupling of phosphonic acids is described in Tet. Lett., (2001) 42:8841, ox Nucleosides & Nucleotides (2000) 19:1885. <br><br>
A number of additional coupling reagents have been described for the preparation of amidates and esters from phosphonic acids. The agents include 30 Aldrithiol-2, and PYBOP and BOP, as described in J! Org. Chem., 1995, 60, 5214, and J. Med. Chem. (1997) 40:3842, mesitylene-2-sulfonyl-3-nitro-l ,2,4-triazole (MSNT), as described in J. Med. Chem. (1996) 39:4958, diphenylphosphoryl azide, as described in J. Org. Chem. (1984) 49:1158,1- <br><br>

Chem., 1988,31, 1305. <br><br>
Phosphonic acids are converted into amidates and esters by means of the Mitsunobu reaction, in which the phosphonic acid and the amine or hydroxy reactant are combined in the presence of a triaryl phosphine and a dialkyl 10 azodicarboxylate. The procedure is described in Org. Lett., 2001, 3,643, or J. Med. Chem., 1997, 40, 3842. <br><br>
Phosphonic esters are also obtained by the reaction between phosphonic acids and halo compounds, in the presence of a suitable base. The method is described, for example, hi Anal. Chem., 1987, 59,1056, or J. Chem. Soc, Perkin 15 Trans., 1,1993,19, 2303, or J. Med. Chem., 1995, 38,1372, or Tet. Lett., 2002, 43,1161. <br><br>
Schemes 34-37 illustrate the conversion of phosphonate esters and phosphonic acids into carboalkoxy-substituted phosphonbisamidates (Scheme 34), phosphonamidates (Scheme 35), phosphonate monoesters (Scheme 36) and 20 phosphonate diesters, (Scheme 37). Scheme 38 illustrates synthesis of gem-dialkyl amino phosphonate reagents. <br><br>
Scheme 34 illustrates various methods for the conversion of phosphonate diesters S34.1 into phosphonbisamidates S34.5. The diester S34.1, prepared as described previously, is hydrolyzed, either to the monoester S34.2 or to the 25 phosphonic acid S34.6. The methods employed for these transformations are described above. The monoester S34.2 is converted into the monoamidate S34.3 by reaction with an aminoester S34.9, in which the group R2 is H or alkyl; the group R4b is a divalent alkylene moiety such as, for example, CHCH3, CHCH2CH3, CH(CH(CH:<)2), CH(CH2Ph), and the like, or a side chain group 30 present in natural or modified aminoacids; and the group R5b is Q-C12 alkyl, such as methyl, ethyl, propyl, isopropyl, or isobutyl; Cg-C^o aryl, such as phenyl or substituted phenyl; or C^-Cio arylalkyl, such as benzyl or benzyhydryl. The reactants are combined in the presence of a coupling agent such as a <br><br>

carbodiimide, for example dicyclohexyl carbodiimide, as described in J. Am. Chem. Soc., (1957) 79:3575, optionally in the presence of an activating agent such as hydroxybenztriazole, to yield the amidate product S34.3. The amidate-forming reaction is also effected in the presence of coupling agents such as BOP, 5 as described in J Org. Chem. (1995) 60:5214, Aldrithiol, PYBOP and similar coupling agents used for the preparation of amides and esters. Alternatively, the reactants S34.2 and S34.9 are transformed into the monoamidate S34.3 by means of a Mitsunobu reaction. The preparation of amidates by means of the Mitsunobu reaction is described in J. Med. Chem. (1995) 38:2742. Equimolar amounts of 10 the reactants are combined in an inert solvent such as tetrahydrofuran in the presence of a triaryl phosphine and a dialkyl azodicarboxylate. The thus-obtained monoamidate ester S34.3 is then transformed into amidate phosphonic acid S34.4. The conditions used for the hydrolysis reaction depend on the nature of the R1 group, as described previously. The phosphonic acid amidate S34.4 is 15 then reacted with an aniinoester S34.9, as described above, to yield the bisamidate product S34.5, in which the amino substituents are the same or different. Alternatively, the phosphonic acid S34.6 may be treated with two different amino ester reagents simulataneously, i.e. S34.9 where R2, R4b or R5b are different. The resulting mixture of bisamidate products S34.5 may then be 20 separable, e.g. by chromatography. <br><br>

An example of this procedure is shown in Scheme 34, Example 1. In this procedure, a dibenzyl phosphonate S34.14 is reacted with diazabicyclooctane 5 (DABCO) in toluene at reflux, as described in J. Org. Chem., 1995, 60,2946, to afford the monobenzyl phosphonate S34.15. The product is then reacted with equimolar amounts of ethyl alaninate S34.16 and dicyclohexyl carbodiimide in pyridine, to yield the amidate product S34.17. The benzyl group is then removed, for example by hydrogenolysis over a palladium catalyst, to give the 10 monoacid product S34.18 which may be unstable according to J. Med. Chem. (1997) 40(23):3842. This compound S34.18 is then reacted in a Mitsunobu reaction with ethyl leucinate S34.19, triphenyl phosphine and diethylazodicarboxylate, as described in J! Med. Chem., 1995,38, 2742, to produce the bisamidate product S34.20. <br><br>
15 Using the above procedures, but employing in place of ethyl leucinate <br><br>
S34.19 or ethyl alaninate S34.16, different aminoesters S34.9, the corresponding products S34.5 are obtained. <br><br>
Alternatively, the phosphonic acid S34.6 is converted into the bisamidate S34.5 by use of the coupling reactions described above. The reaction is 20 performed in one step, in which case the nitrogen-related substituents present in the product S34.5 are the same, or in two steps, in which case the nitrogen-related substituents can be different. <br><br>
An example of the method is shown in Scheme 34, Example 2. In this procedure, a phosphonic acid S34.6 is reacted in pyridine solution with excess 25 ethyl phenylalanmate S34.21 and dicyclohexylcarbodiimide, for example as <br><br>

described in J. Chem. Soc., Chem. Comm., 1991, 1063, to give the bisamidate product S34.22. <br><br>
Using the above procedures, but employing, in place of ethyl phenyl alaninate, different aminoesters S34.9, the corresponding products S34.5 5 are obtained. <br><br>
As a further alternative, the phosphonic acid S34.6 is converted into the mono or bis-activated derivative S34.7, in which Lv is a leaving group such as chloro, imidazolyl, triisopropylbenzenesulfonyloxy etc. The conversion of phosphonic acids into chlorides s34.7 (Lv = CI) is effected by reaction with 10 thionyl chloride or oxalyl chloride and the like, as described in Organic <br><br>
Phosphorus Compounds, G. M, Kosolapoff, L. Maeir, eds, Wiley, 1976, p. 17. The conversion of phosphonic acids into monoimidazolides S34.7 (Lv = imidazolyl) is described in J. Med. Chem., 2002, 45,1284 and in J. Chem. Soc. Chem. Comm., 1991, 312. Alternatively, the phosphonic acid is activated by 15 reaction with triisopropylbenzenesulfbnyl chloride, as described in Nucleosides and Nucleotides, 2000,10, 1885. The activated product is then reacted with the aminoester S34.9, in the presence of a base, to give the bisamidate S34.5. The reaction is performed in one step, in which case the nitrogen substituents present in the product S34.5 are the same, or in two steps, via the intermediate S34.ll, in 20 which case the nitrogen substituents can be different. <br><br>
Examples of these methods are shown in Scheme 34, Examples 3 and 5. In the procedure illustrated in Scheme 34, Example 3, a phosphonic acid S34.6 is reacted with ten molar equivalents of thionyl chloride, as described in Zh. <br><br>
Obschei Khim., 1958, 28,1063, to give the dichloro compound S34.23. The 25 product is then reacted at reflux temperature in a polar aprotic solvent such as acetonitrile, and in the presence of a base such as triethylamine, with butyl serinate S34.24 to afford the bisamidate product S34.25. <br><br>
Using the above procedures, but employing, in place of butyl serinate S34.24, different aminoesters S34.9, the corresponding products S34.5 are 30 obtained. <br><br>
In the procedure illustrated in Scheme 34, Example 5, the phosphonic acid S34.6 is reacted, as described in J. Chem. Soc. Chem. Comm., 1991, 312, with carbonyl diimidazole to give the imidazolide S34.S32. The product is then <br><br>

reacted in acetonitrile solution at ambient temperature, with one molar equivalent of ethyl alaninate S34.33 to yield the monodisplacement product S34.S34. The latter compound is then reacted with carbonyl diimidazole to produce the activated intermediate S34.35, and the product is then reacted, under 5 the same conditions, with ethyl N-methylalaninate §34.33a to give the bisamidate product S34.36. <br><br>
Using the above procedures, but employing, in place of ethyl alaninate S34.33 or ethyl N-methylalaninate S34.33a, different aminoesters S34.9, the corresponding products S34.5 are obtained. <br><br>
10 The intermediate monoamidate S34.3 is also prepared from the monoester S34.2 by first converting the monoester into the activated derivative S34.8 in which Lv is a leaving group such as halo, imidazolyl etc, using the procedures described above. The product S34.8 is then reacted with an aminoester S34.9 in the presence of a base such as pyridine, to give an 15 intermediate monoamidate product S34.3. The latter compound is then converted, by removal of the R1 group and coupling of the product with the aminoester S34.9, as described above, into the bisamidate S34.5. <br><br>
An example of this procedure, in which the phosphonic acid is activated by conversion to the chloro derivative S34.26, is shown in Scheme 34, Example 20 4. In this procedure, the phosphonic monobenzyl ester S34.15 is reacted, in dichloromethane, with thionyl chloride, as described in Tet. Letters1994, 35, 4097, to afford the phosphoryl chloride S34.26. The product is then reacted in acetonitrile solution at ambient temperature with one molar equivalent of ethyl 3-amino-2-methylpropionate S34.27 to yield the monoamidate product S34.28. 25 The latter compound is hydrogenated in ethylacetate over a 5% palladium on carbon catalyst to produce the monoacid product S34.29. The product is subjected to a Mitsunobu coupling procedure, with equimolar amounts of butyl alaninate S34.30, triphenyl phosphine, diethylazodicarboxylate and triethylamine in tetrahydrofuran, to give the bisamidate product S34.31. <br><br>
30 Using the above procedures, but employing, in place of ethyl 3-amino-2- <br><br>
methylpropionate S34.27 or butyl alaninate S34.30, different aminoesters S34.9, the corresponding products S34.5 are obtained. <br><br>

The activated phosphonic acid derivative S34.7 is also converted into the bisamidate S34.5 via the diamino compound S34.10. The conversion of activated phosphonic acid derivatives such as phosphoryl chlorides into the corresponding amino analogs S34.10, by reaction with ammonia, is described in 5 Organic Phosphorus Compounds. G. M. Kosolapoff. L. Maeir, eds, Wiley, 1976. The bisamino compound S34.10 is then reacted at elevated temperature with a haloester S34.12 (Hal = halogen, i.e. F, CI, Br, I), in a polar organic solvent such as dimethylformamide, in the presence of a base such as 4, 4-dimethylaminopyridine (DMAP) or potassium carbonate, to yield the bisamidate 10 S34.5. Alternatively, S34.6 may be treated with two different amino ester reagents simulataneously, i.e. S34.12 where R4b or R5b are different. The resulting mixture of bisamidate products S34.5 may then be separable, e.g. by chromatography. <br><br>
An example of this procedure is shown in Scheme 34, Example 6. In this 15 method, a dichlorophosphonate S34.23 is reacted with ammonia to afford the diamide S34.37. The reaction is performed in aqueous, aqueous alcoholic or alcoholic solution, at reflux temperature. The resulting diamino compound is then reacted with two molar equivalents of ethyl 2-bromo-3-methylbutyrate S34.38, in a polar organic solvent such as N-methylpyrrolidinone at ca. 150 °C, 20 in the presence of a base such as potassium carbonate, and optionally in the presence of a catalytic amount of potassium iodide, to afford the bisamidate product S34.39. <br><br>
Using the above procedures, but employing, in place of ethyl 2-bromo-3-methylbutyrate S34.38, different haloesters S34.12 the corresponding products 25 S34.5 are obtained. <br><br>
■ The procedures shown in Scheme 34 are also applicable to the preparation of bisamidates in which the aminoester moiety incorporates different functional groups. Scheme 34, Example 7 illustrates the preparation of bisamidates derived from tyrosine. In this procedure, the monoimidazolide 30 S34.32 is reacted with propyl tyrosinate S34.40, as described in Example S, to yield the monoamidate S34.41. The product is reacted with carbonyl diimidazole to give the imidazolide S34.42, and this material is reacted with a further molar equivalent of propyl tyrosinate to produce the bisamidate product S34.43. <br><br>

542343 <br><br>
WO 2004/096236 PCT/US2004/013143 <br><br>
Using the above procedures, but employing, in place of propyl tyrosinate S34.40, different aminoesters S34.9, the corresponding products S34.5 axe obtained. The aminoesters employed in the two stages of the above procedure can be the same or different, so that bisamidates with the same or different 5 amino substituents are prepared. <br><br>
Scheme 35 illustrates methods for the preparation of phosphonate monoamidates. <br><br>
In one procedure, a phosphonate monoester S34.1 is converted, as described in Scheme 34, into the activated derivative S34.8. This compound is 10 then reacted, as described above, with an aminoester S34.9, in the presence of a base, to afford the monoamidate product S3S.1. <br><br>
The procedure is illustrated in Scheme 35, Example 1. In this method, a monophenyl phosphonate S35.7 is reacted with, for example, thionyl chloride, as described in J. Gen. Chem. USSR., 1983, 32,367, to give the chloro product 15 S35.8. The product is then reacted, as described in Scheme 34, with ethyl alaninate, S3, to yield the amidate S35.10. <br><br>
Using the above procedures, but employing, in place of ethyl alaninate S35.9, different aminoesters S34.9, the corresponding products S35.1 are obtained. <br><br>
20 I Alternatively, the phosphonate monoester S34.1 is coupled, as described in Scheme 34, with an aminoester S34.9 to produce the amidate, S335.1. If necessary, the R1 substituent is then altered, by initial cleavage to afford the phosphonic acid S35.2. The procedures for this transformation depend on the nature of the R1 group, and are described above. The phosphonic acid is then 25 transformed into the ester amidate product S35.3, by reaction with the hydroxy compound R OH, in which the group R is aryl, heterocycle, alkyl, cycloalkyl, haloalkyl etc, using the same coupling procedures (carbodiimide, Aldrithiol-2, PYBOP, Mitsunobu reaction etc) described in Scheme 34 for the coupling of amines and phosphonic acids. <br><br>

Examples of this method are shown in Scheme 35, Examples and 2 and 5 3. In the sequence shown in Example 2, a monobenzyl phosphonate S35.ll is transformed by reaction with ethyl alaninate, using one of the methods described above, into the monoamidate S35.12. The benzyl group is then removed by catalytic hydrogenation in ethylacetate solution over a 5% palladium on carbon catalyst, to afford tlie phosphonic acid amidate S35.13, The product is then 10 reacted in dichloromethane solution at ambient temperature with equimolar amounts of l-(dimethylaminopropyl)-3-ethylcarbodiimide and trifluoroethanol S35.14, for example as described in Tet. Lett., 2001, 42, 8841, to yield the amidate ester S35.15. <br><br>
In the sequence shown in Scheme 35, Example 3, the monoamidate 15 S35.13 is coupled, in tetrahydrofuran solution at ambient temperature, with equimolar amounts of dicyclohexyl carbodiimide and 4-hydroxy-N-methylpiperidine S35.16, to produce the amidate ester product S35.17. <br><br>
Using the above procedures, but employing, in place of the ethyl alaninate product S35.12 different monoacids S3S.2, and in place of <br><br>

trifluoroethanol S35.14 or 4-hydroxy-N-methylpiperidine S35.16, different hydroxy compounds R3OH, the corresponding products S35.3 are obtained. <br><br>
Alternatively, the activated phosphonate ester S34.8 is reacted with ammonia to yield the amidate S35.4. The product is then reacted, as described in 5 Scheme 34, with a haloester 335.5, in the presence of a base, to produce the amidate product S35.6. If appropriate, the nature of the R1 group is changed, <br><br>
using the procedures described above, to give the product S35.3. The method is illustrated in Scheme 35, Example 4. In this sequence, the monophenyl phosphoryl chloride S35.18 is reacted, as described in Scheme 34, with 10 ammonia, to yield the amino product S35.19. This material is then reacted in N-methylpyrrolidinone solution at 170° with butyl 2-bromo-3-phenylpropionate S3S.20 and potassium carbonate, to afford the amidate product S35.21. <br><br>
Using these procedures, but employing, in place of butyl 2-bromo-3-phenylpropionate S35.20, different haloesters S35.5, the corresponding products 15 S35.6 are obtained. <br><br>
The monoamidate products S35.3 are also prepared from the doubly activated phosphonate derivatives S34.7. In this procedure, examples of which are described in Synlett., 1998,1,73, the intermediate S34.7 is reacted with a limited amount of the aminoester S34.9 to give the mono-displacement product 20 S34.ll. The latter compound is then reacted with the hydroxy compound R3OH in a polar organic solvent such as dimethylformamide, in the presence of a base such as diisopropylethylamine, to yield the monoamidate ester S35.3. <br><br>
The method is illustrated in Scheme 35, Example 5. In this method, the phosphoryl dichloride S35.22 is reacted in dichloromethane solution with one 25 molar equivalent of ethyl N-methyl tyrosinate S35.23 and dimethylaminopyridine, to generate the monoamidate S35.24. The product is then reacted with phenol S3S.25 in dimethylformamide containing potassium carbonate, to yield the ester amidate product S35.26. <br><br>
Using these procedures, but employing, in place of ethyl N-methyl 30 tyrosinate S35.23 or phenol S35.25. the aminoesters 34.9 and/or the hydroxy compounds R3OH, the corresponding products S35.3 are obtained. <br><br>

In one procedure, a phosphonate monoester S34.1, prepared as described above, is coupled, using one of the methods described above, with a hydroxyester S36.1, in which the groups R4b and R5b are as described in Scheme 34. For example, equimolar amounts of the reactants are coupled in the presence 5 of a carbodiimide such as dicyclohexyl carbodiimide, as described in Aust. J. Chem., 1963, 609, optionally in the presence of dimethylaminopyridine, as described in Tet., 1999, 55,12997. The reaction is conducted in an inert solvent at ambient temperature. <br><br>
The procedure is illustrated in Scheme 36, Example 1. hi this method, a 10 monophenyl phosphonate S36.9 is coupled, in dichloromethane solution in the presence of dicyclohexyl carbodiimide, with ethyl 3-hydroxy-2-methylpropionate S36.10 to yield the phosphonate mixed diester S36.ll. <br><br>
Using this procedure, but employing, in place of ethyl 3-hydroxy-2-methylpropionate S36.10, different hydroxyesters S33.1, the corresponding 15 products S33.2 are obtained. <br><br>
The conversion of a phosphonate monoester S34.1 into a mixed diester S3 6.2 is also accomplished by means of a Mitsunobu coupling reaction with the hydroxyester S36.1, as described in Org. Lett., 2001, 643. In this method, the reactants 34.1 and S36.1 are combined in a polar solvent such as tetrahydrofuran, 20 in the presence of a triarylphosphine and a dialkyl azodicarboxylate, to give the mixed diester S36.2. The R1 substituent is varied by cleavage, using the methods described previously, to afford the monoacid product S36.3. The product is then coupled, for example using methods described above, with the hydroxy compound R3OH, to give the diester product S36.4. <br><br>
25 The procedure is illustrated in Scheme 36, Example 2. In this method, a monoallyl phosphonate S36.12 is coupled in tetrahydrofuran solution, in the presence of triphenylphosphine and diethylazodicarboxylate, with ethyl lactate S36.13 to give the mixed diester S36.14. The product is reacted with tris(triphenylphosphine) rhodium chloride (Wilkinson catalyst) in acetonitrile, as 30 described previously, to remove the allyl group and produce the monoacid product S36.15. The latter compound is then coupled, in pyridine solution at ambient temperature, in the presence of dicyclohexyl carbodiimide, with one molar equivalent of 3-hydroxypyridine S36.16 to yield the mixed diester S36.17. <br><br>

The mixed diesters S36.2 are also obtained from the monoesters S34.1 5 via the intermediacy of the activated monoesters §36.5. In this procedure, the monoester S34.1 is converted into the activated compound S36.5 by reaction with, for example, phosphorus pentachloride, as described in J. Org. Chem., 2001, 66, 329, or with thionyl chloride or oxalyl chloride (Lv = CI), or with triisopropylbenzenesulfonyl chloride in pyridine, as described in Nucleosides 10 and Nucleotides, 2000,19,1885, or with carbonyl diimidazole, as described in J. Med. Chem., 2002, 45, 1284. The resultant activated monoester is then reacted with the hydroxyester S36.1, as described above, to yield the mixed diester S36.2. <br><br>
The procedure is illustrated in Scheme 36, Example 3. In this sequence, a 15 monophenyl phosphonate S36.9 is reacted, in acetonitrile solution at 70 °C, with ten equivalents of thionyl chloride, so as to produce the phosphoryl chloride S36.19. The product is then reacted with ethyl 4-carbamoyl-2-hydroxybutyrate S36.20 in dichloromethane containing triethylamine, to give the mixed diester S36.21. <br><br>

carbamoyl-2-hydroxybutyrate S3 6.20, different hydroxyesters S36.1, the corresponding products S36.2 are obtained. <br><br>
The mixed phosphonate diesters are also obtained by an alternative route for incorporation of the R30 group into intermediates S36.3 in which the 25 hydroxyester moiety is already incorporated. In this procedure, the monoacid intermediate S36.3 is converted into the activated derivative S36.6 in which Lv is a leaving group such as chloro, imidazole, and the like, as previously described. The activated intermediate is then reacted with the hydroxy compound R3OII, in the presence of a base, to yield the mixed diester product 30 S36.4. <br><br>
The method is illustrated in Scheme 36, Example 4. In this sequence, the phosphonate monoacid S36.22 is reacted with trichloromethanesulfonyl chloride in tetrahydrofuran containing collidine, as described in J. Med. Chem., 1995, 38, <br><br>

The phosphonate esters S36.4 are also obtained by means of alkylation reactions performed on the monoesters S34.1. The reaction between the 10 monoacid S34.1 and the haloester S36.7 is performed in a polar solvent in the presence of a base such as diisopropylethylamine, as described in Anal. Chem., 1987, 59, 1056, or triethylamine, as described in J. Med. Chem., 1995, 38,1372, or in a non-polar solvent such as benzene, in the presence of 18-crown-6, as described in Syn. Comm., 1995, 25, 3565. <br><br>

Using the above procedure, but employing, in place of butyl lactate S37.5, different hydroxyesters S37.2, the corresponding products S37.3 are 5 obtained. <br><br>
Alternatively, the diesters S37.3 are obtained by alkylation of the phosphonic acid S34.6 with a haloester S37.1. The alkylation reaction is performed as described in Scheme 36 for the preparation of the esters S36.4. <br><br>
This method is illustrated in Scheme 37, Example 2. In this procedure, 10 the phosphonic acid S34.6 is reacted with excess ethyl 3-bromo-2- <br><br>

Example 6 <br><br>
Prednisolone, 6A, is treated in a solvent, such as chloroform, with formaldehyde in the presence of an acid, such as concentrated hydrochloric acid, After stirring for several hours (preferably 7 to 10 hours) at room temperature, the layers are separated and the organic layer is concentrated to afford the bis-(methylenedioxy) intermediate, 5.3 (Hirschmann, R. et al, J.

1964, 86,1520-1527). This intermediate is treated with diethyl (amino-oxymethyl)phosphonate in a solvent such as pyridine to afford the oxime, 5.4. The oxime is treated with aqueous acid to remove the bis-(methylenedioxy) protecting group. For example, the oxime is treated with 60% aqueous formic acid and heated at 90 "C for 10 min., cooled and concentrated using portions of ethanol to assist in removing formic acid. Chromatographic purification and/or crystallization of the residue yield the phosphonate oxime analog, 5.5, of prednisolone. <br><br>
a key precursor of this synthesis, diethyl (aminooxymethyl)phosphonate, can be obtained from diethyl (trifluoromethyl-sulfonyloxymethyl)phosphonate and N-(t-butoxycarbonyl)-hydroxylamine. Accordingly, N-(t-butoxycarbonyl)-hydroxylamine is dissolved in a solvent such as THF and treated with sodium hydride. When bubbling ceases, diethyl (trifluoromethylsulfonyloxymetliyl)-phosphonate (prepared according to Tetrahedron Lett., 1986, 27, 1477) is added. After quenching the reaction with aqueous ammonium chloride and extracting the product with an organic solvent such as ethyl acetate, the N-Boc protected diethyl (aminooxymethyl)phosphonate is isolated by chromatography.

Prednisolone, 6A, is reduced to 1,2-dihydroprednisolone, 7.1, using a rhodium catalysis such as tris(triphenylphosphine)rhodium(I) chloride under hydrogen according to a procedure such as that reported by Procopiou, P. et al, J. Med. Chem., 2001, 44, 602-612. The dihydroxy ketone group on the D ring of the steroid is then protected using the method described in Example 6, before fonnylation at the C-2 position. For example, tlie bis-(methylenedioxy) intermediate, 7.2, is treated with freshly distilled ethyl formate and sodium hydride in a solvent such as toluene. The reaction is quenched with aqueous solution of a weak base such as potassium dihydrogen phosphate. The crude product is purified by a general method such as crystallization, affording the 2-formyl intermediate, 7.3. This 2-formyl compound is condensed with a phosphonate-substituted phenylhydrazine to yield, after removal of the bis-(methylenedioxy) protecting group, the desired phosphonate pyrazole analog, 7.4, of prednisolone. <br><br>

3 -Hydroxy-5-nitro-bejizoic acid is heated briefly in thionyl chloride to generate the acid chloride. The acid chloride is condensed with 0,N-dimethyl-hydroxylamine in the presence of a base such as triethylamine to produce the Weinreb amide which, upon reaction with methyl lithium, provides the" acetophenone derivative. The acetophenone derivative is treated with a base such as potassium carbonate in a dipolar aprotic solvent such as dimethylformamide, in the presence of an excess of E-1 ,4-dibromobutene. The monobromide is isolated by chromatography and then subjected to treatment with triethylphosphite in a solvent such as toluene (or other Arbuzov reaction conditions: see Engcl, R., "Synthesis of Carbon-phosphorus Bonds," CRC press, 1988) to generate the desired phosphonate diethyl ester. Thereafter, the carbonyl of the acetophenone is reduced enantioselectively using an appropriate homochiral oxazaborolidine such as that described by Corey (J. Am. Chem. Soc., 1987,109, 5551), and the resulting alcohol is displaced by azide using a method such as that described by Mitsunobu (Bull. Chem. Soc. Japan., 1971, 44, 34-27).

is H, alkyl, alkenyl, aryl or aralkyl. The phosphonate compounds incorporate a phosphonate moiety (R'O^PCO) connected to the nucleus by means of a variable linking group, designated as "link." <br><br>
For example, the above scheme depicts a protection-deprotection sequence in which the steroid side-chain is protected as a bis-methylenedioxy (BMD) moiety, hi this sequence, Prednisone, 21 A, is reacted with paraformaldehyde and an acid catalyst such as hydrochloric acid, as described in "Protective Groups in Organic Synthesis," by T.W. Greene and P.G.M. Wuts, Wiley, Second Edition 1990, p. 223, to yield the BMD derivative, 21.1. The phosphonate moiety is then introduced, using the procedures described below, to produce the phosphonate ester, 21.2.

ethylene ketal, by reaction in toluene solution at reflux temperature with ethylene glycol and an acid catalyst, as described in / Am. Chem. Soc., 1955, 77, 1904. Deprotection is effected by reaction with pyridinium tosylate in aqueous acetone, as described in J. Chem. Soc., Chem. Comm., 1351, 1987. <br><br>
Alternatively, the 11-ketone is protected by conversion to the N, N-dimethylliydrazone. The dimethyl hydrazone is prepared by the reaction of the ketone, 21.1, with N,N-dimethylhydrazine in ethanol-acetic acid, as described in Org. Syn., 1970, 50, 102. The group is removed by treatment with sodium acetate and acetic acid in aqueous tetrahydrofuran, as described in J. Am. Chem, ' Soc., 1979,101, 5841. <br><br>
Alternatively, the 11-ketone is protected as the diethylamine adduct. In this procedure, the substrate, 21.1, is reacted with titanium tetrakis-(diethylamide), as described in J. Chem. Soc., Chem. Comm., 406, 1983, to afford the adduct. The ketone is deprotected by reaction with water in an aqueous organic solvent. <br><br>

The reaction is conducted between equimolar amounts of the reactants in an aprotic solvent such as pyridine or xylene, or in an alcoholic solvent such as ethanol, optionally in the presence of an acid catalyst, to give the imine or oxime. The preparation of oximes of steroidal 3-ketones is described in Anal. Bioch., 1978, 86, 133 and in J. Mass. Spectrom., 1995, 30,497.

Sundbcrg, Plenum, 2001, p. 503ff and in Acc. Chem. Res., 1919,12,146.

Karo, Academic Press, 1968, p. 274, and "Comprehensive Organic Transformations," by R. C. Larock, VCH, 1989, p. 972ff.

Alternatively, the carboxylic acid may first be converted into an activated derivative such as the acid chloride, anhydride, mixed anhydride, imidazolide and the like, and then reacted with the amine, in the presence of an organic base such as, for example, pyridine, to afford the amide. The conversion of a carboxylic acid into the corresponding acid chloride can be effected by treatment of the carboxylic acid with a reagent such as, for example, thionyl chloride or oxalyl chloride in an inert organic solvent such as dichloromethane, optionally in the presence of a catalytic amount of dimethylformamide. The product, P3.18, is then deprotected to give the diol, P3.19 (which is a compound of Formula 17). <br><br>

A protection-deprotection sequence in which the steroid side-chain is protected as a bis-methylenedioxy (BMD) moiety is shown above. The propionate ester groups of compound, 42.1, are hydrolyzed, for example by reaction with two molar equivalents of lithium hydroxide in aqueous dimethoxyethane solution at ambient temperature, to give the diol, 42.2. The product is then reacted with paraformaldehyde and an acid catalyst such as hydrochloric acid, as described in "Protective Groups in Organic Synthesis," by T.W. Greene and P.G.M. Wuts, Wiley, Second Edition 1990, p. 223, to yield the BMD derivative, 42.3. The phosphonate moiety is then introduced, using the procedures described below, to produce the phosphonate ester, 42.4. Prior to hydrolysis of the BMD protecting group, the 11-hydroxyl group is protected. The protecting group is selected so that it is stable to the conditions required for removal of the BMD group, and so that it is removable without affecting the subsequently introduced 17,21-diester moiety. <br><br>
For example, the 11-hydroxyl group is protected by conversion to the 4-azidobutyrate ester, by reaction with 4-azidobutyryl chloride in pyridine. The 11-azidobutyrate group is then removed from the diester, 42.7, by reaction with triphenylphosphine, as described in Bull. Soc. Chem. Jpn., 1986, 59,1296. <br><br>

Alternatively, the 11-hydroxyl group is protected by conversion to the 2-(tri-methylsilyl)ethyl carbonate, by reaction with 2-(trimethylsilyl)ethyl carbonyl chloride and pyridine. The 2-( trimethylsilyl) carbonate is removed from the diester, 42.7, by reaction with tetrabutylammonium fluoride in tetrahydrofuran at ambient temperature, as described in Tet. Lett., 1981, 22, 969. <br><br>
Alternatively, the 11-hydroxyl group is protected by conversion to the trichloroacetyl ester, by reaction with trichloroacetyl chloride in dimethylform-amide-pyridine.

Second Edition 1990, p. 223, to afford the diol, 42.6. The diol compound is then acylated, for example by reaction with propionic acid and dicyclohexyl carbodiimide in dimethylformamide at ambient temperature, or by reaction with propionyl chloride and triethylamine in dichloromethane, to produce the dipropionate, 42.7. Deprotection of the 11-hydroxyl group, as described above, then affords the diester, 42.8. <br><br>
Alternatively, the 20-ketone group is protected as the diethylamine adduct by reaction with titanium tetrakis(diethylamide), as described in Protective Groups in Organic Synthesis, by T.W. Greene and P.G.M Wuts, Wiley, Second Edition 1990, p. 219. <br><br>

The preparation of arylphosphonates by means of a coupling reaction between aryl bromides and dialkyl phosphites is described in J. Med. Chem., 1992, 35, 1371. The reaction is performed in an inert solvent such as toluene, in the presence of a base such as triethylamine and a catalytic amount of tetralds(triphenyIphosphine)palladium(0). <br><br>
Alternatively, the bromo-substituted product, 45.2, is coupled, in a palladium-catalyzed Heck reaction, with a dialkyl propenyl phosphonate, 45.5, (Acros) to give the unsaturated phosphonate, 45.6. The coupling of aryl halides with olefins by means of the Heck reaction is described, for example, in "Advanced Organic Chemistry," by F. A. Carey and R. J. Sundberg, Plenum, 2001, p. 503ff and in Acc. Chem. Res., 1979,12, 146. The aryl bromide and the olefin are coupled in a polar solvent such as dimethylformamide or dioxan, in 1 the presence of a palladium(O) catalyst such as tetrakis(triphenylphosphine)-palladium(O) or palladium(H) catalyst such as palladium(II) acetate, and optionally in the presence of a base such as triethylamine or potassium carbonate. <br><br>

Wuts, Wiley, Second Edition 1990, p. 223, to yield, the BMD derivative, 55.2. The phosphonate moiety is then introduced, using the procedures described below, to produce the phosphonate ester, 55.3. Prior to hydrolysis of the BMD protecting group, the 11-hydroxyl group is protected. The protecting group is selected so that it is stable to the conditions required for removal of the BMD group, and so that it is removable without affecting the subsequently introduced 17, 21-diester moiety. For example, the 11-hydroxyl group is protected by conversion to the 4-azido-butyrate ester, by reaction with 4-azidobutyryl chloride in pyridine. The 11-azidobutyrate group is then removed from the diester, 55.6, by reaction with triphenylphosphine, as described in Bull. Soc. Chem. Jpn., 1986,59, 1296. Alternatively, the 11-hydroxyl group is protected by conversion to the 2-(tri-methylsilyl)ethyl carbonate, by reaction with 2-(trimethylsilyl)ethyl carbonyl j chloride and pyridine. The 2-(trimethylsilyl) carbonate is removed from the diester, 55.6, by reaction with tetrabutylammonium fluoride in tetrahydrofuran at ambient temperature, as described in Tet. Lett., 1981,22, 969. <br><br>
Alternatively, the 11-hydroxyl group is protected by conversion to the trichloroacetyl ester, by reaction with trichloroacetyl chloride in dimethyl-formamidepyridine. The trichloroacetyl ester is removed by reaction with ethanoiic ammonia at ambient temperature, as described in Coll. Czech. Chem. Commun., 1962, 27, 2567. The BMD moiety in the protected product, 55.4, is then hydrolyzed, for example by treatment with 50% aqueous acetic acid, as described in "Protective Groups in Organic Synthesis," by T.W. Greene and P.G.M. Wuts, Wiley, Second Edition 1990, p. 223, to afford the diol, 55.5. The diol, 55.5, is acylated, for example by reaction with propionic acid and dicyclohexyl carbodiimide in dimethylformamide at ambient temperature, or by reaction with propionyl chloride and triethylamine in dichloromethane, to produce the dipropionate, 55.6. Deprotection of the 11-hydroxyl group, as described above, then affords the diester, 55.7. <br><br>

The product is then reacted, in the presence of a palladium catalyst, with a dialkyl phosphite, 106.3, to afford the phosphonate, 106.4. The preparation of arylphosphonates by means of a coupling reaction between aryl bromides and dialkyl phosphites is described in J. Med. Chem., 1992, 35, 1371. The reaction is performed in an inert solvent such as toluene, in the presence of a base such as triethylamine and a catalytic amount of tetrakis(triphenylphosphine)-palladium(O). The 21-hydroxy group is then converted into the 21-chloro derivative, 106.5. <br><br>

The transformation is effected by means of catalytic hydrogenation, for example using a palladium on carbon catalyst and hydrogen or a hydrogen donor, or by the use of diimide or diborane. The products, 106.7 and 106.9, are then converted into the 21-chloro analogs, 106.8 and 106.10. <br><br>

Alternatively, the substrate, 167.3, is converted into the product, 167.6, by means of the method described in J. Med. Chem., 1987, 30,1581. In this procedure, the 21-hydroxy group is activated by conversion to the 21-mesylate, by reaction with mesyl chloride in pyridine; the mesylate group is then displaced to yield the 21-chloro intermediate, by reaction with lithium chloride in dimethylformamide, and the 17-hydroxyl group is esterified to give the 21-chloro-17-(2-furoate) derivative, 167.6.

Alternatively, the bromo compound, 193.3, is coupled with a dialkyl propenylphosphonate, 193.6, (Aldrich) to afford the phosphonate, 193.7. The coupling of aryl halides with olefins by means of the Heck reaction is described, for example, in F. A. Carey and R. J. Sundberg, Advanced Organic Chemistry, 5Q3ff (Plenum, 2001) and in Acc. Chem. Res., 1979,12, 146. The aryl bromide and the olefin are coupled in a polar solvent such as dimethylformamide or dioxan, in the presence of a palladium(O) catalyst such as tetrakis(triphenyl~ phosphine)palladium(O) or palladium(II) catalyst such as palladium(II) acetate, and optionally in the presence of a base such as triethylamine or potassium carbonate. Optionally, the styrenoid double bond present in the product, 193.7, <br><br>

is reduced, for example by reaction with, diimide, to produce the saturated analog, 193.8. The reduction of olefinic bonds is described in R. C. Larock, Comprehensive Organic Transformations, 6ff (VCH, 1989). The transformation is effected by means of catalytic hydrogenation, for example using a palladium on carbon catalyst and hydrogen or a hydrogen donor, or by the use of diimide or diborane. <br><br>
Using the above procedures, but employing, in place of the bromobenzyl reagent, 193.1, different bromo-substituted aryl or heteroaryl alkoxy hydroxylamines, and/or different dialkyl alkenyl phosphonates, the products analogous to the compounds, 193.5,193.7 and 193.8 are obtained. <br><br>
Example 194 <br><br>
The substrate, 190.1, in which the 20-ketone is protected as the dimethylhydrazone, is reacted with a dialkyl 4-amino-2-furyl phosphonate, 194.1, prepared by the palladium catalyzed coupling reaction, as described above, between 4-amino-2-bromofuran (Tet., 1987,43, 3295) and a dialkyl phosphite, to give, after deprotection, the imine product, 194.2. The imine forming reaction is conducted in a hydrocarbon solvent such as toluene or xylene, at reflux temperature, in the presence of a basic catalyst such as sodium methoxide, or an acid catalyst such as p-toluenesulfonic acid, under azeotropic conditions. <br><br>

The reaction of steroidal l,4-dien-3-ones with hydroxylamines is described in J. Steroid Bioch., 1976, 7, 795; the reaction is perfonned between equimolar amounts of the reactants in a polar organic solvent such as pyridine or methanol, optionally in the presence of acetic acid or sodium acetate. The product, 195.2, is then coupled with a dialkyl 4-aminophenyl phosphonate, 195.3, (Epsilon) and dicyclohexyl carbodiimide, to yield; after deprotection, the amide oxime, 195.4. The preparation of amides from carboxylic acids and derivatives is described, for example, in S.R. Sandler and W. Karo, Organic Functional Group Preparations, 21A (Academic Press, 1968), and R. C. Larock, Comprehensive Organic Transfomiations, 972ff (VCH, 1989). The carboxylic acid is reacted with the amine in the presence of an activating agent, such as, for example, dicyclohexylcarbodiimide or diisopropylcarbodiimide, optionally in the presence of, for example, hydroxybenztriazole, N-hydroxysuccinimide or N-hydroxypyridone, in a non-protic solvent such as, for example, pyridine, DMF or dichloromethane, to afford the amide. <br><br>

Methylprednisolone aceponate, 219A, is protected as its silyl ether using the standard TBSCI and imidazole conditions (J. Am. Chem. Soc., 1972, 94, 6190). Saponification of both ester moieties using aqueous sodium hydroxide provides the diol, 222.2. The less sterically hindered primary hydroxy group is alkylated by the addition of sodium hydroxide and the phosphonate triflate. <br><br>
After treating intermediate, 222.3, with propionic anhydride in pyridine, the previously hydrolized C-17 propionic ester is replaced (J. Med. Chem., 1980, 23, 430-437). TBAF deprotection of the silyl ether furnishes diethyl phosponate, 222.5. <br><br>

Compounds such as 227.1 (where X= O, Z= CILOH), can be prepared according to the procedure of Littler, B. J. et al., 7th International Conference on Organic Process Research and Development, New Orleans, LA, March 16-19, 2003 (Schemes 3 and 4). The starting material, 2-benzyloxyphenylacetic acid, 227.1, (provided by Avocado) can be acylated via the mixed anhydride with the oxazolidinone shown at 80-85 °C, with triethylamine as base to provide compound, 227.2. A low-temperature alkylation with bromoacetonitrile results in the formation of compound, 227.3, with good diastereomeric ratio. Removal of the chiral auxiliary under reductive conditions yields compound, 227.4. without racemization. Protection of the resulting alcohol with the trityl group provides compound, 227.5. Subsequent pyrrole ring construction as well as cyclo-guanidinylation reaction to prepare the six-membered 2-aminopyrimidone ring is performed as described in Example 228 for compound, 228.9, to provide compound, 227.6. <br><br>

Compound, 228.1, (where X= O, Z H) can be prepared according to the general route outlined above. The starting material, 3-(2-benzyloxy-phenyl)~ propionitrile, 228.1, is available by Lewis acid-mediated reaction of phenol with acrylonitrile according to U.S. Patent No. 2,789,995, published in 1954. Intermediate, 227.5, can follow the same synthetic steps as outlined here to provide compound, 227.1. <br><br>
Pyrrole ring construction can be completed in three steps from 3-(2- <br><br>
benzyloxy-phenyl)-propionitrile, 228.1. Formation of 3-hydroxy-acrylonitrile, <br><br>
228.2, can be achieved by exposure of, 228.1, to LDA and ethyl formate. <br><br>
Condensation of this product with 2-Amino-malonic acid diethyl ester in EtOH <br><br>
and sodium acetate yields compound, 228.3, which undergoes a decarboxylative cyclization in the basic medium of NaOH and EtOH to provide pyrrole, 228.4. <br><br>
In case of compound, 227.1, syntliesis, the trityl protecting group on the benzylic alcohol is removed at this stage. Subsequently, guanidinylation reaction using cyanamide provides compound, 228.5, which, upon treatment with sodium hydroxide, cyclizes to form the 2-aminopyrimidone ring (compound, 228.6), <br><br>

Preparation of DADMeTnnnG is reported in Lewandowics A. et al, Biochemistry, 2003, 42, 6057. The tertiary nitrogen of the ring may not interfere with the alkylation of the secondary alcohol and in that case does not need to be protected, although standard protection and deprotection protocols as described in Greene, T., Protective Groups in Organic Synthesis, Wiley-Interscience, 1999 may be used if necessary.

The preparation of the phosphonatesis illustrated above. Specifically, compound 239.1, 5-hydroxy-1 -(4-hydroxy-5 -hydroxymethyl-tetrahydrofuran-2-ylmethyl)-lH-imidazole-4-carboxylic acid amide, is first protected using a TBS group. Subsequent oxidation with PtC>2 proceeds to provide carboxylic acid 240.1. Decarboxylative elimination is achieved using dimethylformamide dineopentyl acetal in DMF at high temperature (Zemlicka J. et al., J. Am. Chem. Soc., 1972, 94, 9, 3213). Once the furanoid glycal 240.2 is in hand, it is treated with silver perchlorate in the presence of diethyl(hydroxylmethyl)phosphonate (Phillion, D. et al., Tetrahedron Lett, 1986,27, 1477) to provide the phosphonate 240.3 (Kim, C. et al., J. Org. Chem., 1991, 56,2642). Oxidative elimination of the selenide followed by dihydroxylation using osmium tetraoxide provides a diol, 240.5, with the desired stereochemistry. Deprotection of the TBS group can be achieved using TBAF to provide compound 240.6. <br><br>

Aldehyde, 246.2, is then treated with a amine phosphonic acid ester of the general formula 246.3 under reductive amination conditions to afford amine, 246.4. The preparation of amines by means of reductive amination procedures is described, for example, in "Comprehensive Organic Transformations," by R. C. Larock, 2nd edition, p. 835. In this procedure, the amine component and the aldehyde component are reacted together in the presence of a reducing agent such as, for example, borane, sodium cyanoborohydride or diisobutylaluminum hydride, to yield the amine product. Finally, deprotection of the hydroxyl group following procedures documented in Greene and Wuts, "Protecting Groups in Organic Synthesis," 3rd Edition, John Wiley and Sons Inc. pi 16-121 gives the phosphonate 246.5. <br><br>

Subsequent protection of the primary alcohol using a TBS group can be achieved using TBSCI and imidazole in solvents such as CFLCl?. as described in Greene, T., "Protective Groups in Organic Synthesis," Wiley-Interscience, 1999 to provide compound, 261.1. Compound, 261.1, is then treated in a solvent such as tetrahydrofuran or dimethylformamide with a base such as sodium hydride. When bubbling ceases, diethyl phosphonomethyltriflate (prepared according to Tetrahedron Lett., 1986, 27,1477) is added, yielding a mixture of the desired phosphonate diester, 261.2, and 261.3, after deprotection of the BOC group using trifluoroacetic acid (TFA). Compounds, 261.2, and 261.3, can be also prepared via a more complicated 2' OH protected analog of compound 261.1 followed by alkylation using the diethyl phosphonomethyltriflate to provide compound 261.2, exclusively.

After the phenolic OH is protected with a suitable protecting group, for example benzyl group, the compound 269.21 is synthesized by the same procedure described in U.S. Patent No. 6,054,472, and U.S. Patent No. 6,344,465. After the protecting group is removed, the phosphonate containing moiety is introduced to the phenolic OH using the phosphonate reagent 269.7, bearing a suitable leaving group.

For example, a solution of 269.22, which is obtained by the procedure of Norio et al. (Tetrahedron Lett. 1992, 33(37), 5403), is treated with sodium hydride and one equivalent of benzyl bromide in DMF to get 269.23. <br><br>
Compound 269.23 is converted to 269.24 by a series of steps such as those reported in U.S. Patent No. 6,054,472, and U.S. Patent No. 6,344,465. After the benzyl protecting group of 269.24 is removed by catalytic hydrogenation, a phosphonate bearing moiety is attached by alkylation of the resulting phenol in <br><br>

Representative compounds of the invention can be prepared as illustrated above. Compound 270.26 is treated with carbonyldiimidazole or triphosgene followed by the compound 270.27, which has a handle to attach phosphonate moiety. Compound 270.27 bearing an extra substituent is synthesized from the tri substituted phenol with a cyano and a nitro groups, which is either commercially available or by literature procedures (Zolfigol, M. A. et. al. Indian J. Chem. Sect. B 2001, 40,1191; De Jongh, R. O. et al. Reel. Trav. Chim. Pays-Bas 1968, 87, 1327). The resulting 270.28 is converted to 270.29 using procedures similar to those described in U.S. Patent No. 6,054,472, and U.S. Patent No. 6,344,465. The phosphonate moiety of 270.6 is attached after deprotection of the benzyl group of 270.29. <br><br>

For example, the bromine substituent of compound 270.30 is substituted with cyano group by the procedure of De Jongh, R. O. et al. (Reel. Trav. Chim. Pays-Bas 1968, 87,1327) and the methoxy group is converted to benzyloxy group as a protecting group, which affords compound 270.31. After selective reduction of cyano to aminomethyl group by borane. the amino group is protected with Boc group and then the reduction of the nitro group using tin (II) chloride generates compound 270.32. This substituted aniline 270.32 is then treated with a reaction mixture of the compound 270.26 and carbonyldiimidazole, as described in U.S. Patent No. 6,054,472, and U.S. Patent No. 6,344,465, to form the urea 270.33. Compound 270.33 is converted to 270.34. Deprotection of the benzyl group using catalytic hydrogenation <br><br>

More specifically, the preparation of generic structure, 273A are described inNagahara, et al J. Med. Chem.; 33; 1990; 407-415. The structure 273.2 is described in Kini, et al J. Med. Chem.; 34; 1991; 3006-3010. The two patents cited above also provided examples of the synthesis of compound, 273A. <br><br>
The core components of this reaction sequence are the transformation of compound from 273.3 to 273.6. Appropriate oxidant(s) can convert the primary alcohol (5'-hydroxy) shown in 273.3 to a carboxylic acid or its corresponding ester, hi the case of an ester, an additional deprotection step will give the carboxylic acid, 273.4. A variety of oxidation procedures exist in the literature and can be utilized here. These include but are not limited to the following methods: (i) pyridinium dicliromate in Ac205 t-BuOH, and dichloromethane producing the t-butyl ester, followed by a depretection using reagent such as trifluoroacetic acid to convert the ester to the corresponding carboxylic acid (see Classon, et al., Acta Chem. Scand. Ser. B; 1985, 39, 501-504. Cristalli, et al., J. Med. Chem., 1988, 31, 1179-1183.); (ii) iodobenzene diacetate and 2,2,6.6-tetramethyl-l-piperidinyloxy, free radical (TEMPO) in acetonitrile, producing <br><br>

WO 2004/096236 PCT/US2004/013143 <br><br>
the carboxylic acid (See Epp, et al; J. Org. Chem. 64; 1999; 293-295. Jung et al; J. Org. Chem.; 66; 2001; 2624-2635.); (iii) sodium periodate, ruthenium(III) chloride in chloroform producing the carboxylic acid (see Kim, et al, J Med. <br><br>
Chem. 37; 1994; 4020-4030. Homma, et al; J. Med. Chem.; 35; 1992; 2881-2890); (iv) chromium trioxide in acetic acid producing the carboxylic acid (see Olsson et al; J. Med. Chem.; 29; 1986; 1683-1689. Gallo-Rodriguez et al; J. Med. Chem.; 37; 1994; 636-646); (v) potassium permanganate in aqueous potassium hydroxide producing the carboxylic acid (see Ha, et al; J. Med. <br><br>
Chem.; 29; 1986; 1683-1689. Franchetti, et al; J Med. Chem,; 41; 1998; 1708-1715.) (vi) nucleoside oxidase from S. maltophilia to give the carboxylic acid (see Mahmoudian, et al; Tetrahedron; 54; 1998; 8171-8182.) <br><br>
The preparation of compound 273.5 starting with compound 273.4 using lead(IV) tetraacetate (Lv = OAc) was described by Teng et al; J. Org. Chem.; 59; 1994; 278-280 and Schultz, et al; J. Org. Chem.; 48; 1983; 3408-3412. <br><br>
When lead(IV) tetraacetate is used together with lithium chloride (see Kochi, et al; J. Am. Chem, Soc.; 87; 1965; 2052), the corresponding chloride is obtained (273.5, Lv = Cl). Lead(IV) tetraacetate in combination with N-chlorosuccinimide can produce the same product (273.5, Lv = Cl) (see Wang, et . al; Tet. Asynu; 1; 1990; 527 and Wilson et al; Tet. Asym.; 1; 1990; 525). Alternatively, the acetate leaving group (Lv) can also be converted to other leaving group such as bromide by treatment of trimethylsilyl bromide to give 273.5 ((see Spencer, et al; J. Org. Chem.; 64; 1999; 3987-3995). <br><br>
The coupling of 273.5 (Lv = OAc) with a variety of nucleophiles were described by Teng et al; Synlett; 1996; 346-348 and U.S. Patent No. 6,087,482; Column 54 line 64 to Column 55 line 20. Specifically, the coupling between 273.5 and diethyl hydroxymethylphosphonate in the presence of trimethylsilyl trifluoromethanesulfonate (TMS-OTf) was described. It can be envisioned that other compounds with the general structure of HO-linker-PORP1RF2 can also be used so long as the functional groups in these compounds are compatible with the coupling reaction conditions. There are many examples in the published literature describing the coupling of 273.5 (Lv = halogen) with a variety of alcohols. The reactions can be facilitated with a number of reagents, such as silver(I) salts (see Kim et al; J. Org. Chem.; 56; 1991; 2642-2647, Toikka et al; <br><br>

J. Chem. Soc. Perkins Trans. 1; 13; 1999; 1877-1884), mercury(II) salts (see Veeneman et al; Reel. Trav. Chim. Pays-Bas; 106; 1987; 129-131), boron trifluoride diethyl etherate (see Kunz et al; Hel. Chim Acta; 68; 1985; 283-287), Tin(n) chloride (see O'Leary et al; J. Org. Chem.; 59; 1994; 6629-6636), aikoxide (see Shortnacy-Fowler et al; Nucleosides Nucleotides; 20; 2001; 1583-1598), and iodine (see Kartha et al; J. Chem. Soc. Perkins Trans. 1; 2001; 770-772). These methods can be selectively used in conjunction with different methods in forming 273,5 with various leaving groups (Lv) to produce 273.6. <br><br>
The transformations from 273.1 to 273.2, from 273.2 to 273.3, and from 273.6 to 273.7 are intended to allow the core components of the transformations (from 273.3 to 273.6) to occur while preserving the functional groups already exist in the compound structures. Thus, the syntheses may require the introduction and removal of protecting groups from a compound is a commonly practiced art in organic synthesis. It should be understood that in the transformation 273.6 to 273.7, RP1 and RP2 do not need to remain unchanged. The final form of RP1 and Rp2 can be selected from a variety of possible structures. <br><br>

Compound 274.1 is prepared using the method described in the patent application WO 01/90121 (table at page 115). The 5'~hydroxyl in 274.1 is protected as a terr-butyldimethylsilyl (TBDMS) ether. The 2'- and 3'- hydroxyl groups can be protected as bezoyl (Bz) esters to give 274.2. The 5'-hydroxyl can then be deprotected to give 274.3. Oxidation using iodobenzene diacetate and 2,2,6,6-tetramelhyl-l-piperidinyloxy, free radical (TEMPO) convert the primary alcohol to the corresponding acid 274.4. Further oxidation of 274.4 using lead tetraacetate can produce 274.S. Coupling between 274.S and diethyl hydroxy-rnethyl-phosphonate (available from Sigma-Aldrich, Cat. No. 39,262-6) effected by TMS-OTf can afford 274.6. Treating 274.6 with TMS-Br converts the phosphodiester to the corresponing phosphonic acid 274.7. Deprotection of the 2'- and 3'- hydroxyl gives 274.8 as an example of the generic structure A, where Base is an 7-thia-8-oxo-guanosine, R , R , R and R are hydrogen, linker is a methylene group. <br><br>
The phosphonic acids in 274.7 and 274.8 are used as examples for illustration purpose. Other forms of phosphonates can be access via the phosphonic acid, or other forms, such as the corresponding diesters as described herein. <br><br>

Representative compounds of the invention can be prepared as illustrated above. The carboxylic acid of mycophenolic acid can be replaced with a phosphonic acid that may also serves as a prodrug handle. In order to remove the carboxylic acid containing side chain, the acid chloride 290.5 (prepared in Example 289) is converted to ester 290.1. Protection of the phenol with a silyl group, followed by dihydroxylation and cleavage of the diol generates aldehyde 290.3 (Pankiewicz, et al., J. Med. Chem., 2002, 45, 703), (Patterson et al., U.S. Patent No. 5,444,072). A Wittig reaction with ylide 290.4 carrying an appropriately protected phosphonate provides the desired compound 290.5. <br><br>
Final deprotection yields compound 290.6. A specific compound of tie invention can be prepared as follows. <br><br>

Mycophenolate ester 290.8 can simply be prepared by stirring the acid chloride 290.7 with MeOH. Then, the phenol position of mycophenolate ester is protected by a silyl group such as TBS to provide compound 290.9. Once the phenol position is protected, dihydroxylation using osmium tetraoxide followed by periodinate cleavage provides aldehyde 290.10. Aldehyde 290.10 and excess of the ylide 290.11 are heated in benzene at reflux for about 24 hours. The reaction mixture is concentrated and the residue is purified by column chromatography to provide olefin 290.12 (Parikiewics et al., J. Med. Chem., 2002, 45, 703). A final deprotection using HF-pyridine yields the final product 290.13. <br><br>

Representative compounds of the invention can be prepared as illustrated above. Another attachement point of the compound can be unmasked after demethylation of mycophenolate ester 291.2 as illustrated above. For this purpose, the 4-OH needs to be masked with a protecting group (P) such as a silyl group. Once the 6-MeO is demethylated and alkylated, the protecting group at position 4 is removed to reveal the final product 291.4. The morphonyl ethanol group is installed early and carried through the alkylation steps. A different protecting group may be installed initially and removed later. In such the latter type of synthesis, the last step is the formation of the morpholinoethyl ester prodrug. A specific compound of the invention can be prepared as described below. <br><br>

Phenol 291.5 is protected with TBS group in CH2CI2 using imidazole as base to yield 291.6. Demethylation is performed using thiolate nucleophiles to generate compound 291.7. A variety of other methods are also available in literature as described in Protective Groups in Organic Synthesis by Greene and Wuts. Alklation of the 6-OH using a triflate of the phosphonate proceeds well using K2CO3 or TEA to provide 291.8. Final deprotection to remove the TBS group provides product 291.9. <br><br>

The phenols shown herein may optionally be alkylated with the reagent of choice. Optionally, the phosphonate moiety will be part of such a reagent. Alternatively, it will be introduced in a subsequent step by a variety of means, of wliich three are illustrated above. For example, an alkyl halide may be heated with triethylphosphite in a solvent such as toluene (or other Arbuzov reaction conditions: see Engel, R., "Synthesis of Carbon-phosphorus Bonds," CRC press, 1988). Alternatively, an epoxide may be reacted with the anion of a dialkyl phosphinate. In a further example, the phosphonate reagent may be the electrophile, e.g., an acetylide anion may be condensed with phosphorus oxychloride and the intermediate dichlorophosphonate quenched with ethanol to generate the diethyl ester of the desired phosphonic acid. <br><br>

Example 348 <br><br>
By way of example and not limitation, embodiments of the invention are named below in tabular format (Table 100). These embodiments are of the general formula "MBF": <br><br>
O <br><br>
Sc <br><br>
Lg <br><br>
~Pd <br><br>
Pd1 <br><br>
MBF <br><br>
Each embodiment of MBF is depicted as a substituted nucleus (Sc). Sc is described in formula 1-151 herein, wherein A0 is the point of covalent attachment of Sc to Lg, as well as inTables 1.1 to 1.5 below. For those 10 embodiments described in Table 100, Sc is a nucleus designated by a number and each substituent is designated in order by letter or number. Tables 1.1 to 1.5 are a schedule of nuclei used in forming the embodiments of Table 100. Each nucleus (Sc) is given a number designation from Tables 1.1 to 1.5, and this designation appears first in each embodiment name. Similarly, Tables 10.1 to 15 10.19 and 20.1 to 20.36 list the selected linking groups (Lg) and prodrug (Pd1 and Pd2) substituents, again by letter or number designation, respectively. Accordingly, a compound of the formula MBF includes compounds having Sc groups based on formula 1-151 herein as well as compounds according to Table 100 below. In all cases, compounds of the formula MBF have groups Lg, Pd1 20 and Pd2 setforth in the Tables below. <br><br>
Accordingly, each named embodiment of Table 100 is depicted by a number designating the nucleus from Table 1.1-1.5, followed by a letter designating the linking group (Lg) from Table 10.1-10.19, and two numbers designating the two prodrug groups (Pd1 and Pd2) from Table 20.1-20.36. In 25 graphical tabular form, each embodiment of Table 100 appears as a name having the syntax: <br><br>
Sc.Lg.Pd^Pd2 <br><br>

WO 2004/096236 PCT/US2004/013143 <br><br>
Each Sc group is shown having a tilda The tilda is the point of covalent attachment of Sc to Lg. Q1 and Q2 of the linking groups (Lg), it should be understood, do not represent groups or atoms but are simply connectivity 5 designations. Q1 is the site of the covalent bond to the nucleus (Sc) and Q2 is the site of the covalent bond to the phosphorous atom of formula MBF. Each prodrug group (Pd1 and Pd2) are covalently bonded to the phosphorous atom of MBF at the tilda symbol ("-")• Some embodiments of Tables 10.1-10.19 and 20.1-20.36 maybe designated as a combination of letters and numbers (Table 10 10.1-10.19) or number and letter (Table 20.1-20.36). For example there are Table 10 entries for BJ1 andBJ2. In any event, entries ofTable 10.1-10.19 always begin with a letter and those ofTable 20.1-20.36 always begin with a number. When a nucleus (Sc) is shown enclosed within square brackets ("[]") and a covalent bond extends outside the brackets, the point of covalent 15 attachment of Sc to Lg may be at any substitutable site on SC, Selection of the point of attachment is described herein. By way of example and not limitation, the point of attachment is selected from those depicted in the schemes and examples. <br><br>
