Synthesizing of The compounds of this invention
As mentioned above, preferably by suitable dione compounds being fed the host cell of giving modified microorganism (containing the 6-dEB PKS expression system of having rejected KS1) or methyl being provided in the C-13 position, then the polyketide that obtains is fed and (change to the red saccharopolyspora recombinant bacterial strain, do not produce 6-dEB), preparation is used for the microbiotic parent material of the present invention of any further chemosynthesis.Can prepare can hydroxylation 6-and the 12-position or the bacterial strain of hydroxylation 12-position only.In the later case ,-H replaced-OR fIn addition, can prepare the only bacterial strain of hydroxylation 6-position.Pass through homologous recombination, the transformant that obtains now can not produce the 6-dEB as substrate polyketide competition thing, but produce 6-position and 12-position hydroxylation, 3-position and the glycosylation of 5-position of the modification polyketide of polyketide transformant generation streptomycete or other.If macrolide only has 12-position hydroxylation, and does not need 6-position hydroxylation (OR fReplaced by H), can make up the red saccharopolyspora bacterial strain by the eryF '-hydroxylase gene that interrupts among the bacterial strain K40-67.In addition, can make the eryK gene lose function, can be easy to generate the embodiment of compound (1)-(3), wherein R aBe H.
The glycosylation that produces erythromycin generates and diglycosyl form like the naturally occurring erythromycin series.If the compound of formula (3) will prepare from initial product, the hydroxyl of the cladinose ring that needs protection so (with 3 bindings), macrolide is substituent to be modified subsequently to be suitable for.
The erythromycin that the present invention modifies also can contain-OH at 6 except the C-13 position is modified, unless as above-mentioned OR fReplaced by H.(wherein 6 is OR for the compound of structure formula (1), (2) and (3) f), the compound of the formula (3) with blocking group is provided, form R cAnd R eAn embodiment.With suitable these protections of protection reagent is effectively, realizes in non-proton solution as diacetyl oxide, benzoyl oxide, chloroformic acid benzyl ester, hexamethyldisilazane or trialkylsilkl chlorine.Suitable aprotic solvent comprises methylene dichloride, chloroform, tetrahydrofuran (THF), N-Methyl pyrrolidone, methyl-sulphoxide (DMSO), dimethyl formamide (DMF) etc.Usable mixtures also.The protection of two sugared hydroxyls can simultaneously or successively be carried out in the formula (3).
" the hydroxyl, also must protect the ketone group of 9 on macrolide ring except protecting 2 ' and 4 of two glucosyl residues.Usually this realizes by ketone group being changed into the deutero-oxime.The particularly preferred example of R comprises not alkyl (1-12C), replacement or unsubstituted aryl (6-10C), alkyl (1-12C), replacement or the unsubstituted heteroaryl (6-10C), alkyl (1-12C) and the assorted alkyl that replace or replace (formula CR ' for example among formula=NOR 2The substituting group of OR, wherein each R ' except above-mentioned R distinguishes the such of illustration, can form cycloalkyl ring (3-12C) altogether with other).Preferred deutero-oxime is formula=NOR, and wherein R is the isopropoxy cyclohexyl.
9-ketone group and 2 ' and 4 " after hydroxyl is protected, can be by in the presence of alkali, reacting with alkylating reagent, the 6-hydroxyl in the alkylation precursor becomes the compound of formula (3).Alkylating reagent comprises alkyl halide and sulphonate.For example, alkylating reagent can comprise toluenesulphonic acids methyl esters, 2-fluoro ethyl bromine, cinnamyl bromine, crotyl bromide, allyl bromide 98, propargyl bromide etc.In the presence of alkali (as potassium hydroxide, sodium hydride, potassium isopropoxide, potassium tert.-butoxide) and aprotic solvent, carry out alkylation.
Particularly preferred R fBe methyl, allyl group and ethyl.
In case finished the alkylation of 6-hydroxyl, saccharide residue and macrolide ring can go protection.Glucosides part go protection as Green, T.W. etc., Protect Groups in Organic Synthesis, following.Similarly condition causes the deutero-oxime is changed into=NOH.If the formation of deutero-oxime does not take place simultaneously with going protection, can carry out the conversion of oxime separately.
Can take off oxime then and change into ketone group with standard method known in the art.Take off the oxime agent and comprise inorganic oxysulfide, as sodium bisulfite, sodium pyrosulfate, Sulfothiorine etc.At this point, can use protic solvent, as pure and mild their mixture of water, methyl alcohol, ethanol, Virahol, trimethyl silane.In general, in the presence of organic acid, carry out de-oxime reaction.
In the process this point or after, the compound of formula (3) can further operate in the group of introducing on the 6-hydroxyl after being converted to the compound of the formula (1) that hereinafter further describes or (2).It (is O-CH that initial replacement can provide the 6-O-allyl group easily 2CH=CH 2), it can obtain 6-O propylated compound, or handle with perosmic anhydride further by the reduction derivatize, obtains 2,3-dihydroxypropyl compound, its further esterification on each Sauerstoffatom.Also available metachloroperbenzoic acid is oxidation O-allyl deriv in aprotic solvent, obtains epoxy compounds, and its available amine or contain the heteroaryl compound open loop of N obtains containing the compound of the side chain of N, or can oxidation under the Wacker condition, obtains substituting group O-CH 2-C (O)-CH 3, or but ozonize obtains aldehyde.Aldehyde can be changed into oxime then, or with the reaction of suitable amine, and in the presence of the borohydride reductive agent, reduce, obtain amine.Also can oxime be changed into nitrile by in aprotic solvent, reacting with dehydrated reagent.Also can make O-allyl deriv and aryl halide in Heck condition (Pd (II) or Pd (O), phosphine and amine or mineral alkali) reaction down, obtain 3-arylprop-2-thiazolinyl derivative.Use hydrogen and this derivative of palladium carbon reduction then, obtain 3-arylpropyl derivative.If initial substituent R fBe the 2-propine, available similar reaction changes side chain, comprises arylation.
For the compound of formula (3) being transformed the compound of an accepted way of doing sth (1), by at first removing the cladinose group, with weakly acidic aqueous solution or go Glycosylase to handle the compound of formula (3).Suitable acid comprises the alcoholic solution of hydrochloric acid, sulfuric acid, Mono Chloro Acetic Acid, trifluoroacetic acid etc.Normally 0.5-24 hour reaction times, temperature is-10-35 ℃.In this reaction process, protect 2 ' group of the sugar that stays as mentioned above, going to go protection after the cladinose reaction then.Then the hydroxyl of the macrolide ring 3-position that obtains is oxidized to ketone with the Swern oxidation style of improvement.In the method, use oxygenant, as N-chloro-succinimide-dimethyl sulphide or carbide diamide-methyl-sulphoxide.Usually, in chlorinated solvent such as methylene dichloride, under-10-25 ℃ in preformed N-chloro-succinimide and dimethyl sulphide mixture the compound of adding formula (3).Stir after 0.5-4 hour, add tertiary amine (as triethylamine), produce corresponding ketone, remove 2 ' blocking group then.
For at 2 halogenation macrolides (with R bBe transformed into halogen from H), with the compound of alkali and close electric halogenating agent (as perbromo-pyridine or N-fluorobenzene sulfonic acid) processing formula (1).After having prepared 3 ketone compounds, 2 of halogenations at any time are preferably after 11,12 rings form.
Can further operate the suitable substituent of C-13 position, as vinyl (vinyl), ethylidine (ethenyl), butenyl or azido-.For example, the derive amido acetate of The compounds of this invention of available aryl Acetyl Chloride 98Min. obtains the arylamino alkyl on the C-13 position.The C13 of preferred azido-derives and forms preceding generation at ketone compound.Deriving of ethylidine can take place before and after ketone compound forms.
For the compound of acquisition formula (2), handle the compound that obtains from formula (1) de-glycosylation reaction with dewatering agent (as carbonyl dimidazoles and alkali).
For the compound (wherein one of Z and Y are H, and the OH of another OH or protection is above-mentioned aminoderivative) of preparation formula (1)-(3), carbonyl or oxime or deutero-oxime use appropriate reductant (as sodium borohydride, Raney nickel/H 2) reduction, or with sodium cyanoborohydride and the ammonification of amine reductibility.Also can obtain the amine of replacement by alkylation.
The compounds of this invention synthetic novel method also is provided.
