A mild and efficient Cu2O-catalyzed domino intramolecular C–N coupling/C–Y (Y = O, S, N) bond formation was successfully achieved. Thus oxazino[3,2-a]indole, thiazino[3,2-a]indole and indolo[2,1-b]quinazoline derivatives were facilely assembled from readily accessible gem-dibromovinyl systems. The protocol is general and practical, affording a variety of the indole-incorporated products in good to
成功实现了温和有效的Cu 2 O催化的多米诺骨牌分子内C–N偶联/ C–Y(Y = O,S,N)键的形成。因此,恶唑并[3,2- a ]吲哚,噻嗪并[3,2- a ]吲哚和吲哚并[2,1- b ]喹唑啉衍生物是从容易得到的宝石-二溴乙烯基系统容易地组装而成的。该方案是通用且实用的,即使在空气气氛下,也能以优异的产率提供各种掺入吲哚的产品。
