(LX) is treated successively with H2O2 and LiOH, with triethylsilyl trifluoromethylsulfonate and with water to afford acid (LXI). Cyclization of (LXI) with 2-chloro-N-methylpyridinium iodide and triethylamine in dichloromethane yields the cyclic derivative (LXII), which is treated with 2,3-dichloro-5,6-dicyanobenzoquinone (DDQ) to eliminate the 4-methoxybenzyl protecting group, so yielding alcohol (LXIII). A new partial deprotection of (LXIII) with trifluoroacetic acid affords the glycol (LXIV), which is oxidized with oxalyl chloride in DMSO to the vicinal triketone (LXV). Treatment of (LXV) with HF in acetonitrile gives the epoxy derivative (LXVI) with some free hydroxyl groups which are protected with triethylsilyl chloride, affording the compound (LXVII) with only one free hydroxy group. Oxidation of (LXVII) with Dess-Martin periodinane (DMP) in dichloromethane yields protected FK-506 (LXVIII), which is finally deprotected with HF in acetonitrile.

The macrocyclization of (LI) by means of EDC and DMAP in dichloromethane gives the macrolactone (LII), which is treated with DDQ and oxidized with DMP in dichloromethane to yield the tricarbonyl compound (LIII). The cyclization and desilylation of (LIII) by means of HF in acetonitrile affords the tricyclic macrolactone (LIV), which is treated with Tes-Cl and oxidized with DMP to provide the silylated precursor (LV). Finally, this compound is desilylated with HF in acetonitrile to give the target FK-506.
