合成路线1
该中间体在本合成路线中的序号：(XIII)Compound (XVI) was prepared by solid phase peptide synthesis on a Rink amide 4-methylbenzhydrylamine (MBHA) resin. To the Thr-bound resin (XI) they were stepwise coupled in subsequent coupling and deprotecting cycles the following amino acids: Fmoc-Tyr(t-Bu)OH (XII), and Fmoc- (N-allyloxycarbonylaminoethyl)PheOH (XIV) to yield the corresponding peptide-bound resins (XIII) and (XV), respectively. Then, allyl and allyoxycarbonyl protecting groups were both removed from the linear peptide-bound resin (XV) by treatment with tetrakis(triphenylphosphine)palladium, acetic acid, and N-methylmorpholine (NMM) in chloroform to yield compound (XVI).
