合成路线1
该中间体在本合成路线中的序号：(XVI)2) The methylation of meso-2,6-bis(benzyloxycarbonylamino)heptanedioic acid (I) with diazomethane gives the corresponding dimethyl ester (XIII), which is submitted to a selective hydrolysis with a protease type VIII enzyme yielding the monoester (XIV). The cyclization of (XIV) with PCl5 affords the oxazolidinedione (XV), which is condensed with D-alanine 4-nitrobenzyl ester (XVI) to give compound (XVII) with a free amino group that is condensed with D-glutamic acid monoester (XI) affording the fully protected FK-565 derivative (XVIII), which is first debenzylated by hydrogenolysis to methyl ester (XIX), and finally hydrolyzed with NaOH.
