hydroxylamine glycine derivatives, acting as imine surrogates via an interrupted Polonovski reaction, is described to access functionalized amino acid derivatives. The addition of C, N, O, and S nucleophiles was achieved in a one-pot procedure in 37% to 92% yield. This method could be extended to dipeptide derivatives for the functionalization of both the C-terminus and N-terminus.
氨基甲酸酯保护的羟胺甘氨酸衍生物的 α-官能化,通过中断的 Polonovski 反应充当亚胺替代物,被描述为获得官能化的氨基酸衍生物。 C、N、O 和 S 亲核试剂的添加通过一锅法实现,产率为 37% 至 92%。该方法可以扩展到二肽衍生物,以实现 C 端和 N 端的功能化。
