本研究重点拓展了镍催化多肽α-C-Ts亲电试剂与芳基/乙烯基卤化物的非对映选择性反应的底物范围. 特别是, 利用广泛的杂芳基卤化物实现高效的肽骨架α-C后期修饰, 并对含C端TsG单元的二肽进行芳基化, 这在我们之前的报道中尚未涉及. 因此, 本研究提供了更多有趣的α-C-芳基/乙烯基单元修饰肽的实例, 这些修饰肽在药物开发中构建模块具有潜在应用价值.

This work highlights our continuous efforts to expand the substrate scope of the Ni-catalyzed diastereoselective reaction of peptide α-C-Ts with aryl/vinyl halides. In particular, this work is focused on efficient late-stage peptide backbone α-C-modulation with a wide range of heteroaryl halides, and the arylation of dipeptides containing the TsG unit at the C- terminals, which has not been investigated in our previous report. Thus, this study provides more interesting examples of peptides modified with α-C-aryl/vinyl groups, which could serve as useful building blocks for drug development.

Key words: arylation, vinylation, nickel, peptide
