A copper-catalyzed multicomponent reaction of sulfonyl azides, alkynes, and allylamines affording 2,3-dihydro-1H-imidazo-[1,2-a]indoles in moderate yields is reported. Four C–N bonds are constructed by way of azide-alkyne cycloaddition (CuAAC) and double Ullmann-type coupling reactions in a one-pot process.
据报道,铜催化的磺酰叠氮化物,炔烃和烯丙胺的多组分反应以中等收率提供了2,3-二氢-1 H-咪唑-[1,2-a]吲哚。一锅法通过叠氮化物-炔烃环加成(CuAAC)和双重Ullmann型偶联反应构建四个C–N键。
