合成路线1
该中间体在本合成路线中的序号：(XI)Solution-phase synthesis: Protection of the side-chain of Boc-Arg-OH (IX) by treatment with Cbz-Cl in aqueous NaHCO3 yields Boc-Arg(Cbz)-OH (X), which is then converted into arginine lactam (XI) by a first treatment with isobutyl chloroformate (i-BuO2CCl) and NMM in THF followed by Boc deprotection with HCl/dioxane. Condensation of N-deprotected lactam (XI) with protected dipeptide (XII) by means of BOP/DIEA in DMF provides the tripeptide lactam (XIII), which is finally reduced with LiAlH4 in THF and hydrogenated over Pd/C for protecting group removal.
