合成路线1
该中间体在本合成路线中的序号：(XV)Cleavage of both the Z protecting group and ethyl ester of derivative (IX) with HBr in HOAc, followed by the introduction of a Boc group by treatment with Boc2O in dioxane in the presence of NaOH, affords (X), which is then anchored to the resin via its Cs salt to yield (XI). Deprotection of the amine moiety of (XI) with TFA in the presence of EDT as a scavenger, followed by coupling with Boc-Ser(Bzl)-OH in the presence of BOP and DIEA, affords (XII). The peptidic chain is then elongated by successive deprotection with TFA/EDT and coupling of protected amino acids (Boc-Igl-OH (XIV), Boc-Gly-OH(XVI), Boc-Hyp-OH(XVIII) and Boc-Pro-OH(XX) with BOP/DIEA, providing derivative (XXI). (Scheme 28946801b).
