Developed is an unprecedented Au(I)-catalyzed syn-1,2-difunctionalization of ynamides with 2-aminobenzonitriles via nitrile activation. The coupling between ynamides and 2-aminobenzonitriles is explicitly regioselective, providing a straightforward access to 2,4-diamino-substituted quinolines. Density functional theory (DFT) study provides insightful information and rationalizes the reaction pathway
通过腈活化,开发了前所未有的Au(I)催化的2-(2-氨基苄腈)酰胺类的Au(I)催化syn -1,2-双官能化。乙酰胺和2-氨基苄腈之间的偶联具有明确的区域选择性,可直接获得2,4-二氨基取代的喹啉。密度泛函理论(DFT)研究提供了有见地的信息并合理化了反应途径。它显示了Au(I)催化剂在酰胺π活化和腈σ配位之间的协同作用如何使环化可行。
