A facile, site‐selective, and divergent approach to construct 2‐aminopyrroles and quinoline‐fused polyazaheterocycles enabled by a simple gold(III) catalyst from ynamides and anthranils under mild reaction conditions is described. This one‐pot strategy uses readily available starting materials, proceeds in a highly step‐ and atom‐economical manner, with broad substrate scope and scale‐up potential
描述了一种在温和的反应条件下,通过简单的金(III)催化剂从乙酰胺和邻氨基苯甲酸酯中构建2-氨基吡咯和喹啉稠合的聚氮杂环杂环化合物的简便,定点和分散的方法。这种单罐策略使用容易获得的起始原料,以高度一步步和原子经济的方式进行,具有广阔的底物范围和扩大规模的潜力。在该串联反应中成功的关键要素是通过催化剂引导的,优选的通过在酰胺上的亲核苄基-2-呋喃甲基甲基部分猝灭原位生成的金卡宾中间体,以替代已知的CHH环化生成吲哚的方法。
