Efficient syntheses of O-acyl Tyr-peptides allow chemical long-range ligation (O-acyl to N-acyl transfer) via each of 12- to 19-membered cyclic transition states. The results represent the first examples of successful isopeptide ligations starting from O-acyl Tyr-peptides.
高效合成 O-酰基 Tyr-肽允许通过每个 12 至 19 元环过渡态进行化学远程连接(O-酰基到 N-酰基转移)。这些结果代表了从 O-酰基 Tyr-肽起始成功进行类肽连接的第一个实例。
