合成路线1
该中间体在本合成路线中的序号：(LV)5) A second coupling reaction was the addition of the phosphonamide (XX) to the aldehyde (LI) by means of butyllithium in THF to give the dithianylolefin (LII), which was treated first with TFIB and methanol and then with acetic acid, yielding the free aldeyde (LIII). The condensation of (LIII) with methyl 2-(2,4-dimethoxybenzyloxy)acetate (LIV) by means of lithium diisopropylamide in THF, followed by a treatment with LiOH affords the hydroxy acid (LV), which is protected with TES trifluoromethylsulfonate and treated with 2,6-dimethylpyridine to give the free amino acid (LVI), the open-chain precursor of FK-506.
