合成路线1
该中间体在本合成路线中的序号：(XXXIII)The reduction of the tetrahydropyranone group of (XXX) by means of Li(s-Bu)3BH gives the tetrahydropyranol (XXXI), which is iodinated by means of PPh3 and iodine to give the iodo derivative (XXXII). The reaction of the alpha diketonic group of (XXXII) with KHMDS and TesCl yields the silyl enol ether (XXXIII). The fragmentation of the iodinated spiroketal group of (XXXIII) was achieved using a Zn-Ag couple, that was prepared in situ by reduction of ZnCl2 and AgOAc by means of C8K (a mixture of graphite and potassium heated at 150 C under argon) to provide the silylated precursor (XXXIV). Finally the silylated enol ether group of (XXXIV) is hydroxylated by means of dimethyldioxirane and desilylated by means of HF to afford the target FK-506.
