Indole synthesis by a gold(I)‐catalyzed intermolecular formal [4+2] reaction between 1,3‐diynes and pyrroles has been developed. This reaction involves the hydroarylation of 1,3‐diynes with pyrroles followed by an intramolecular hydroarylation to give the 4,7‐disubstituted indoles. This reaction can also be applied to the synthesis of carbazoles when indoles are used as the nucleophiles instead of
已开发了由金(I)催化的1,3-二炔与吡咯之间的分子间形式[4 + 2]反应的吲哚合成。该反应涉及将1,3-二炔与吡咯进行加氢芳基化反应,然后进行分子内加氢芳基化反应,得到4,7-二取代的吲哚。当吲哚代替吡咯用作亲核试剂时,该反应也可用于咔唑的合成。
