合成路线1
该中间体在本合成路线中的序号：(IV)D-Phenylglycine (I) was converted to ethyl ester (II) by means of ethanol and thionyl chloride. Coupling of N-Fmoc-S-benzylcysteine (III) with amino ester (II) produced the protected dipeptide (IV). The Fmoc group of (IV) was then removed by treatment with piperidine in DMF to give (V). N-Fmoc-glutamic acid alpha-benzyl ester (VII) was prepared by reaction of glutamic acid alpha-benzyl ester (VI) with N-(fluorenylmethoxycarbonyloxy)succinimide. Coupling of protected glutamic acid (VII) with dipeptide (V) furnished tripeptide (VIII). The Fmoc and ester protecting groups of (VIII) were finally cleaved by treatment with NaOH.
