The first gold-catalyzed addition of N-arylhydroxylamines to aliphatic terminal alkynes is developed to access O-alkenyl-N-arylhydroxylamines, which undergo facile in situ sequential 3,3-rearrangements and cyclodehydrations to afford 2-alkylindoles with regiospecificity and under exceptionally mild reaction conditions.
首次开发了金催化 N-芳基羟胺与脂肪族末端炔的加成反应,从而获得 O-烯基-N-芳基羟胺,并在极其温和的反应条件下,通过简便的原位顺序 3,3-重排和环脱水反应,得到具有区域特异性的 2-烷基吲哚。
