Abstract

A highly electrophilic copper enalcarbenoid has been disclosed here for the first time for its carbenoid reactivity. The synthetic utility of the transient Cu-enalcarbenoids has been demonstrated in the Cu-catalyzed direct synthesis of 1,7-disubstituted indoles from diazoenals and N-substituted pyrroles. In this reaction, Cu-enalcarbenoid served as a 4[C] biselectrophilic synthon whereas pyrrole served as a 2[C] bisnucleophilie leading to [4+2] benzannulation.

铜烯碳酰胺：通过重氮烯醛和 N-取代的吡咯之间的 [4+2] 苯并annulation 快速获得 1,7-二取代的吲哚

这里首次公开了一种具有高度亲电性的铜烯碳化合物，它具有类羰基化合物的反应活性。在铜催化下，重氮烯醛和 N-取代的吡咯直接合成 1,7-二取代吲哚的过程中，证明了瞬时铜烯碳烯酮的合成用途。在该反应中，Cu-烯碳化合物作为 4[C] 双亲电合成体，而吡咯作为 2[C] 双亲核体，导致 [4+2] 苯并反应。

期刊介绍： Accounts of Chemical Research presents short, concise and critical articles offering easy-to-read overviews of basic research and applications in all areas of chemistry and biochemistry. These short reviews focus on research from the author’s own laboratory and are designed to teach the reader about a research project. In addition, Accounts of Chemical Research publishes commentaries that give an informed opinion on a current research problem. Special Issues online are devoted to a single topic of unusual activity and significance. Accounts of Chemical Research replaces the traditional article abstract with an article "Conspectus." These entries synopsize the research affording the reader a closer look at the content and significance of an article. Through this provision of a more detailed description of the article contents, the Conspectus enhances the article's discoverability by search engines and the exposure for the research.
