A new method for oxidative synthesis of amides from alkynes and amines in high yields (up to 96%) using [Mn(2,6-Cl2TPP)Cl] 1 as a catalyst and Oxone/H2O2 as an oxidant in aqueous medium has been developed. This method could be used for N-terminal α-amino group ligation of unprotected peptides with aryl, aliphatic, and internal alkynes under mild conditions.
开发了一种使用 [Mn(2,6-Cl2TPP)Cl] 1 作为催化剂和 Oxone/H2O2 作为氧化剂在水性介质中以高收率(高达 96%)从炔烃和胺氧化合成酰胺的新方法. 该方法可用于在温和条件下将未受保护的肽与芳基、脂肪族和内部炔烃的 N 端 α-氨基连接。
