合成路线1
该中间体在本合成路线中的序号:(LX)The cyclization of (LVI) by means of N-methyl-2-chloropyridinium iodide and triethylamine yields the macrocyclic lactam (LVII), which is selectively deprotected with trifluoroacetic acid in THF - water and oxidized with DMP in dichloromethane affording the beta-keto lactam (LVIII). Selective deprotection of (LVIII) with DDQ in dichloromethane - tert-butyl alcohol gives the diol (LIX), which is then oxidized with DMP in dichloromethane yielding the silylated FK-506 (LX). Finally, this compound is deprotected by treatment with HF in acetonitrile.

合成路线2
该中间体在本合成路线中的序号:(LIII)The condensation of carbaldehyde (XLVIII) with the chiral intermediate phosphonamide (XXXII), by means of BuLi, gives the adduct (XLIX), which is treated with phenyliodonium trifluoroacetate and AcOH to cleave the 1,3-dithiane ring and yield the carbaldehyde (L). The cyclocondensation of (L) with 2-(2,4-dimethoxybenzyloxy)acetic acid methyl ester (LI) by means of LDA, LiOH, TesOTf and 2-chloro-1-methylpyridinium iodide (CMPI) affords the macrolactone (LII), which is submitted to a sequence of deprotection (DDQ), oxidation (DMP), deprotection (TFA) and oxidation (DMP) to provide the tricarbonyl compound (LIII). A similar sequence (TFA, DMP, DDQ, and DMP) can also be used to obtain the tricarbonyl compound (LIII). Finally this compound is fully desilylated by means of HF in acetonitrile to provide the target FK-506.
