合成路线1
该中间体在本合成路线中的序号：(XIII)The deprotection of Wang-RESIN-coupled N-Fmoc-D-aspartic acid alpha-methyl ester (XII) with piperidine in DMF gives the free RESIN-coupled aspartic acid monoester (XIII), which is condensed with N-Fmoc-sarcosine (XIV) by means of PyBOP in DMF to yield the dipeptide (XV). Deprotection with piperidine affords (XVI), and coupling with PyBOP was repeated with the L-glutamate (XVII) to afford tripeptide (XVIII); with deprotected (XIX) and the intermediate amino acid (XI) to provide tetrapeptide (XX); and with deprotected (XXI) and -Fmoc-L-phenylalanine (XXII) to furnish finally the protected RESIN-bounded pentapeptide (XXIII).
