合成路线1
该中间体在本合成路线中的序号：(XXV)The reaction of the dianhydride (II) with benzyl carbazate (E) gives the bis(benzyloxycarbonylhydrazide) compound (XXI), which by an enzymatic treatment with an aminopeptidase from Streptomyces sapporonensis yields the monohydrazide (XXII). The protection of (XXII) with benzyloxycarbonyl chloride (B) affords the protected monohydrazide (XXIII), which is cyclized by treatment with SOCl2 giving the monocarboxy anhydride (XXIV). Hydrolysis of (XXIV) with HCl yields amino acid (XXV), which is condensed with glycine (XXVI) to afford the dipeptide (XXVII). The condensation of (XXVII) with (X) gives the protected FK-156 (XXVIII), which is debenzylated by hydrogenolysis with H2 over Pd/C in methanol-acetic acid affording FK-156 still protected with an acetoxy and a hydrazine group (XXIX).
