合成路线1
该中间体在本合成路线中的序号：(XXIa),(XXII)The treatment of (XVIII) with Troc-Cl and pyridine gives fully protected (XIX) as the same diastereomeric mixture, which is selectively deprotected at the Sem group with TFA in dichloromethane to yield the corresponding mixture of hydroxyacids (XX). The macrolactonization of (XX) by the Yamaguchi method (2,4,6-trichlrobenzoyl chloride, TEA and DMAP in toluene) gives the diastereomeric mixture of lactones (XXI), which are readily separated by flash column chromatography. The desired diastereomer (XXII) is desilylated with HF and pyridine, yielding the hydroxylactone (XXIII), which is treated with Zn and NH4Cl in refluxing aqueous methanol to eliminate the Troc protecting group and provide the unprotected precursor (XXIV). Finally, this compound is epoxidated with methyl(trifluoromethyl)dioxirane (MTFDO) to afford the target epothilone B.

合成路线4
该中间体在本合成路线中的序号：(XVI)The reaction of 4-methyl-4-penten-1-ol (I) with PBr3 gives the corresponding alkyl bromide (II), which is condensed with epoxide (III) and propyne (IV) by means of Mg, CuI and pentynyl lithium to yield, after silylation with Tbdms-Cl, the protected diol (V). The selective deprotection of (V) with DDQ gives the secondary alcohol (VI), which is oxidized by the Swern reagent to afford the ketone (VII). Alternatively, ketone (VII) can also be obtained by direct oxidation of the protected diol (V) with the Jones reagent. The Horner Emmons condensation of ketone (VII) with phosphonate (VIII) provides the unsaturated alkyl thiazole (IX), which is treated with (Ipc)2BH and sodium formate in THF to give the secondary alcohol (X). The oxidation of (X) with the complex SO3/Pyr yields the carbaldehyde (XI). Alternatively, (XI) can also be obtained by direct oxidation of the terminal double bond of (IX) with (Ipc)2BH and pyridinium chlorochromate (PCC). The condensation of aldehyde (XI) with ketoacid (XII) by means of LDA in THF affords the heptadecadienoic acid (XIII), which is silylated with Tbdms-OTf to provide the protected linear precursor (XIV). The cyclization of (XIV) by means of 2,4,6-trichlorobenzoyl chloride and DMAP in pyridine gives the protected cyclic precursor (XV), which is finally desilylated by means of TBAF in THF to yield the target epothilone D.
