A facile method for the one-pot synthesis of 1,2-diarylindoles under transition-metal-free conditions is described. Cyclohexanones were used as the aryl sources via the dehydrogenative aromatization process. One C–C and two C–N bonds were selectively formed via a domino reaction. This protocol provides a convenient approach for the construction of valuable bioactive 1,2-diarylindoles from readily available
描述了一种在无过渡金属的条件下单罐合成1,2-二芳基吲哚的简便方法。环己酮通过脱氢芳构化过程用作芳基源。通过多米诺反应选择性地形成一个C–C和两个C–N键。该协议为从容易获得的环己酮,α-羟基酮和苯胺构建有价值的生物活性1,2-二芳基吲哚提供了便利的方法。
