合成路线1
该中间体在本合成路线中的序号：(II)The cyclization of 2,2'-di(benzyloxycarbonylamino)pimelic acid (I) with PCl5 in methylene chloride gives the bis-N-carboxy anhydride (II), which by reaction with tert-butyl carbazate (A) is converted into the bis(tert-butyloxycarbonylhydrazide) compound (III). The enzymatic hydrolysis of (III) with an aminopeptidase from Streptomyces sapporonensis affords the mono-tert-butoxycarbonylhydrazide (IV), which by selective protection of the amino group with benzyloxycarbonyl chloride (B) under copper chelate conditions yields the selectively protected hydrazide (V). Full protection of (V) with tert-butoxycarbonyl anhydride (C) affords the fully protected monohydrazide (VI), which is condensed with benzyl glycinate (VII) to give the protected dipeptide (VIII). Hydrogenolysis of (VIII) with H2 over Pd/C in methanol-acetic acid yields the di-tert-butoxycarbonyldipeptide (IX), which is condensed with 2-acetoxypropanoylalanylglutamic acid monobenzyl ester (X) by means of isobutoxycarbonyl chloride (D) yielding the protected FK-156 (XI).

Elimination of the benzyloxycarbonyl groups of (IX) by hydrogenolysis yields compound (X) with a free amino group, which is condensed with N-heptanoyl-D-glutamic acid 1-benzyl monoester (XI) to give the protected FK-565 precursor (XII). Finally, this compound is deprotected with trifluoroacetic acid and sodium periodate.
