A highly efficient and simple route for the synthesis of pyrrolo-/indolo[1,2-a]quinolines and naphtho[2,1-b]thiophenes from gem-dibromovinyls and sulphonamides is reported. The noteworthy feature of this report is that the methodology involves a two-step protocol to synthesize tri- and tetracyclic heterocycles in a one-pot fashion through the Cu(I)-catalyzed formation of ynamide followed by a Ag(I)-assisted
报道了一种由宝石-二溴乙烯基和磺酰胺合成吡咯并//吲哚并[1,2- a ]喹啉和萘并[2,1- b ]噻吩的高效简单途径。该报告的值得注意的特点是该方法涉及两步协议,即通过一锅法通过Cu(I)催化的乙酰胺的形成,然后由Ag(I)辅助的分子内合成三环和四环杂环。氢芳基化。还研究了在固态和溶液态的吡咯并-和吲哚并[1,2- a ]喹啉的代表性实例的光物理性质。
