A copper-based system allows for the methylene insertion between an amine and a milder nucleophile, including a terminal alkyne counterpart, via C–N bond cleavage of N,N-dimethylacetamide. The method gives an expedient access to propargylic amines in good to excellent yields. A wide-ranging substrate scope and late-stage functionalization of complex molecules make the protocol practically valuable
铜基系统允许通过N , N-二甲基乙酰胺的 C-N 键断裂,在胺和较温和的亲核试剂(包括末端炔烃对应物)之间插入亚甲基。该方法可以方便地以良好到极好的收率获得炔丙基胺。广泛的底物范围和复杂分子的后期功能化使该协议具有实际价值。
