Definitions
- the present invention relates to a process for synthesising polymerisable ethylenically unsaturated phosphodiester compounds using phosphite reactants.
- Phospholipids are phosphate diester compounds, in which one of the alcohol residues is generally a glycerol derivative, and the other is a derivative of a different alcohol which may include a nonionic, cationic or, rarely, anionic functionality.
- Phospholipids and phospholipid analogues are of increasing interest, for instance to allow mimicking of cell membrane surfaces to provide useful properties in respect of biocompatibility, he ocompatibility, and to influence the reactions of various biomolecules with surfaces.
- O-A-9416749 describe various synthetic phospholipid analogues and their use to produce devices having biocompatible and hemocompatible surfaces. These specifications in particular describe zwitterionic phospholipid analogues, especially phosphoryl choline derivatives. It is desirable to produce these phospholipid analogues using wholly synthetic methods.
- HEMA-PC itself was first described by Nakabayashi et al in JP-A-54-063025 (1979). In that publication the synthesis involved the reaction of 2-hydroxy ethylmethacrylate with 2-bromoethylphosphoryl dichloride, followed by amination of the bromine substituent of the phosphodiester. Although the process described by Nakaya
- Phosphoramidite chemistry has been developed in the recent past for the synthesis of oligonucleutides. These synthesis are generally carried out on an insoluble support to which a nucieoside is covalently bound. Nucleotides are sequentially added using nucieoside phosphoramidites as relatively stable monofunctional phosphitylating agent synthons, as described first by Beaucage and Caruthers, Tet. Letts. 22, 1859 (1981) and McBride and Caruthers Tet. Letts. 24, 245 (1983). Originally the intermediate was made by reacting chloro-N,N-dimethylaminomethoxyphosphine with an appropriately protected nucieoside.

- they represent a C 2 _ 12 , preferably C 2 . 4 - alkylene chain, most preferably (CH 2 ) 2 .
- the compound of the formula II is reacted in a second step, ii) , in solution in the presence of a weak acid with a second alcohol R OH, in which R' is selected from BR (as defined above) and C.,.
- the process may involve the further iii) step of oxidising the compound of the formula III or of the formula II in which Z is OR to form the corresponding phosphate of the general formula IV
- Y, R and B represent the same groups as in the starting phosphite triester material and R is either R or R 4 .
- An oxidation step of the process of the invention is generally followed by the following step: iv) the compound of the formula IV is deblocked so that the substituent Y is replaced by O * or OH.
- the alcohol used in the first phosphitylating step is the alcohol used in the first phosphitylating step.
- BR OH which is an acrylic type ethylenically unsaturated group, preferably R is hydrogen, methyl, or ethyl, more preferably methyl, so that the alcohol BR OH is an acrylic acid, methacrylic acid or ethacrylic acid derivative.

- the first alcohol is a hydroxy alkyl methacrylate compound, preferably hydroxyethyl methacrylate.
- group Z of the compound of the formula I is a group NR 2 , that is where the compound of the formula I is a difunctional phosphitylating agent and where the product compound is intended to contain one ethylenically unsaturated moiety
- the process is such that only one of the groups NR 2 and NR 2 2 is replaced by the alcohol moiety.
- the groups NR 1 2 and NR 2 2 are different, this is achieved by using reaction conditions such that only one of the groups will react. Any alcoholysis step is conveniently carried out in the presence of a weak acid.
- selective activation for instance of bisphosphoramidite compounds of the formula I is achieved by appropriate selection of weak acid activating agents for the group NR 1 2 and NR 2 2 in the presence of a suitable solvent for the reaction step.
- a suitable solvent for the reaction step For instance an acid that is capable of activating the first - group NR 2 or NR 2 should be used for the first step, whilst a different acid can be used for the activation of the second group NR 2 or NR 2 in the second step.
- Y is a phosphate protecting group, is reacted in solution with a first alcohol R 3 OH in which R 3 is selected from C,_ 40 straight or branched -alkyl groups, -alkenyl groups and -alkynyl groups, any of which may be unsubstituted or substituted by aryl groups, hydroxyl groups, halogen atoms, amine (including mono-, di- or tri ⁇ alkyl substituted amine) groups, sulphonium or phosphonium groups, in the substantial absence of water to form a compound of the general formula VI
- the introduction of a cationic group is necessary where neither of groups R 4 or R3 contains a sulphonium, amino (including an ammonio group) or phosophonium group, but does contain a halogen substituent.
- the reaction is generally the amination of such a halo ⁇ alkyl compound using a tertiary amine, so as to provide a quaternary ammonium group.
- R 3 and R4 i.s a halogen substituted alkyl group
- this can be aminated to replace the halogen atom by a quaternary ammonium group using a tri lower alkylamine, for instance the same tri lower alkylamine used as the base in the
- This aspect of the invention is of particular value for producing phosphonium derivatives and in one particularly preferred embodiment of the second aspect of this invention the cationic group is a phosphonium group.
- this group is often convenient for this group to be a substituent on one of the alcohols R 3OH or R4OH. In such an embodiment, there is no requirement for the introduction of a cationic substituent in step viii) .
- This aspect is also of value for synthesising phospholipid analogues, that is glyceryl derivatives.
- at least one of R OH and R 4 OH is a disubstituted glycerol preferably an ⁇ , / .-disubstituted glycerol, such as an ⁇ ,jS-diacyl, ⁇ ,/J-dialkyl, ⁇ ,/3-dialkenyl or ⁇ ,j8-dialkynyl glycerol.
- the acyl, alkyl, alkenyl or alkynyl groups are, usually, 12-24 carbon atoms in length, preferably 12 to 18 carbon atoms in length and may be different or, preferably, the same as one another.
- the groups R and R represent any of those groups which have been used in phosphoramidite based nucleic acid synthesis processes.
- the groups may all be methyl or other lower alkyl, it is preferred for the groups each to represent alkyl having at least 3 carbon atoms, usually branched alkyl or for the groups R and the nitrogen to which it is attached (and/or R and the nitrogen to which they are attached) to represent saturated or unsaturated heterocyclic groups.
- the groups R or R may thus represent a straight or branched C 2 . 12 -alkylene group for instance a (CH 2 ) 2 .
- the quaternising group may be the same as or different from the group R or R . Examples of
- quaternised derivatives of groups NR 2 and NR 2 are N,N,N- trimethylammonium and N,N,N-triisopropyl ammonium group.
- Preferred unsaturated heterocyclic groups NR 2 or NR 2 are pyridinium and 2,6-dimethylpyridinium.
- any of the weak acids used in phosphate diester synthesis can be used in the or each phosphitylating step, for instance lH-tetrazole, 1,2,4-triazole, 3-chlorotriazole or diisopropylammonium tetrazolide or 4,5- dichloroimidazole.
- weak acids which are cheaper and more readily available than those conventionally used in phosphoramidite phosphitylation reactions can be used successfully.
- weak acids are, for instance, organic acids, preferably carboxylic acids and may be mono- or di-basic.
- groups R are the same or different and each represents branched or straight alkyl groups (including cycloalkyl) or, together with the nitrogen atom to which they are attached, form a heterocycle optionally containing other heteroatoms and being saturated or unsaturated, and NR 2 optionally being in quaternised form,

- Z is either NR 2 in which the groups R are selected from the same groups as R and is the same or different to
- the weak carboxylic acid may be, for instance, a mono basic acid such as benzoic acid, or, preferably, dibasic alkanedioic acid or aromatic diacid such as glutaric acid, phthalic acid, adipic acid or cyanuric acid.
- a mono basic acid such as benzoic acid
- dibasic alkanedioic acid or aromatic diacid such as glutaric acid, phthalic acid, adipic acid or cyanuric acid.
- conventional oxidising systems and agents may be used.
- the substituent groups do not include water sensitive groups, it may be suitable to carry out the oxidation using aqueous iodine with 2,6-lutidine or pyridine catalyst.
- organic oxidising agents such as peroxides, such as tert-butylhydroperoxide, di-te_ ⁇ t butylhydroperoxide, bis-trimethylsilylhydroperoxide, perbenzoic acid derivatives such as meta-chloroperbenzoic acid or iodobenzene diacetate may be used.
- peroxides such as tert-butylhydroperoxide, di-te_ ⁇ t butylhydroperoxide, bis-trimethylsilylhydroperoxide, perbenzoic acid derivatives such as meta-chloroperbenzoic acid or iodobenzene diacetate
- ozone or molecular oxygen in benzene or other dry organic solvent optionally with free radical generators, or dinitrogen tetroxide or other nitrogen oxide oxidising - agents (such as tertiary amine oxides) may be used.
- an amine oxide oxidising agent is used especially where the alcohol which is phosphitylated is BR OH since such oxidising agents give relatively good yields of desired product without by-product formation, especially without formation of by-products of side reactions where the ethylenic bond in a group B is attacked.
- Suitable solvents for steps i) , v) and vi) are tetrahydrofuran, l-methyl-2-pyrrolidinone, chloroform, or, preferably dichloromethane or acetonitrile. Since the phosphite compounds are often water sensitive, it is desirable for the reaction mixtures for steps i) and ii) to be carried out in the substantial absence of water. It may be necessary to dry the reagents and solvents and/or to carry out the reaction under dry inert gas.
- Y is a protecting group, preferably one which, where the process involves subsequent steps, can subsequently be removed from the product of an oxidation step iii) and step vii) , by the use of base. It is usually R 5 0- in which R 5 is a C,_ 6 alkyl group or an aryl group, preferably substituted with an electron withdrawing group, such as halogen atoms, nitro groups, sulphonyl groups, and aryl (including heteroaryl) groups. Substituents in R may additionally provide steric hindrance (for instance 1,1- dialkyl substituents on an alkyl group) .
- R 5 may represent a methyl group, it preferably represents a lower alkyl group with an electron withdrawing substituent such as an aryl group, a cyano group, a vinyl group.
- Preferred groups R are allyl, benzyl, phenyl, phenylsulphoethyl, methyl-sulphoethyl, para-nitrophenylethyl, 2,2,2- trihaloethyl (especially trichloro-and tribromo-ethyl) , 2,2, 2-trihalo-l, 1,-dialkylethyl (especially 2,2,2,- trichloro-1, 1-dimethylethyl, 2'-and 4'-pyridylethyl, m- methylbenzyl, p- or m-halobenzyl, m,p-dichlorobenzyl, pentahalophenyl (especially pentafluoro- and pentachloro ⁇ phenyl) 2, 6-
- step iv) and step viii) is carried out using conventional means.
- thiolates may be used, for instance using the processes described by Daub et al in JACS, 99, 3526 (1977) and by Andreus et al in Tet. Letts, 29, 5479 (1988), it is preferred to avoid the difficult subsequent recovery from, for instance thiophenol byproduct, by using organic base, especially tri lower alkylamine, usually trimethylamine, in organic solvent.
- Suitable solvents are acetonitrile, as well as mixtures of acetonitrile and dichloromethane, methanol/chloroform mixtures or even aqueous lower alcohol mixtures.
- a deblocking step effectively opens the ring to leave an -o " and a group derived from Y-R -0-.
- Such a ring opening step may simultaneously aminate the distal end of the moiety Y, so as to form an amine group, usually a quaternary group.
- the simultaneous reaction thus involves reaction with a trialkylamine in an organic solvent, and is thus an analogous to the ring opening step described by Thuong and Chabrier (op cit) , by Nakaya et al and in our co-pending applications Nos WO-A-9514701 and WO-A-9514702.
- amidite phosphitylating agents allow the process of the invention to proceed with yields of more than 90% or higher whereas the phosphitylation using chlorophosphite phosphitylating agents as described by Podashova et al (op. cit.) can give lower yields e.g. 60%.
