合成路线1
该中间体在本合成路线中的序号：(XVII)Condensation of carbonate (XIV) with N-alpha-Cbz-lysine methyl ester (XV) afforded the carbamate (XVI). The benzyl ester and N-Cbz protecting groups of (XVI) were then removed by catalytic hydrogenolysis, yielding amino acid (XVII), which was subjected to intramolecular cyclization in the presence of BOP to furnish the macrocyclic compound (XVIII). After conversion of the phenolic hydroxyl of (XVIII) to the aryl triflate (XIX), Suzuki coupling with 2-(trifluoromethyl)phenylboronic acid (XX) provided the biphenyl derivative (XXI).
