By employing copper dibromide as a catalyst, Michael addition–condensation of 3‐substituted indoles with α,β‐unsaturated ketimines was realized. The reactions afforded a large variety of 9H‐pyrrolo[1,2‐α]indoles with good yields (up to 99 %). In addition, a plausible reaction mechanism was proposed.
通过使用二溴化铜作为催化剂,可以实现3-取代的吲哚与α,β-不饱和酮亚胺的迈克尔加成-缩合反应。反应提供了多种9H-吡咯并[1,2- α ]吲哚,产率高(高达99%)。另外,提出了合理的反应机理。
