Cu-mediated regioselective, dehydrogenative homocoupling of indoles was developed using AgNO3 as the additive. The easily installed and removed N-pyrimidyl group exerted complete C2 regiocontrol via C–H activation. A series of indole substrates underwent cross-dehydrogenative-homocoupling. This work developed an effective approach for the synthesis of 2,2′-biindole core of a number of chemicals fundamentally
使用AgNO 3作为添加剂,开发了铜介导的吲哚区域选择性,脱氢均偶联。易于安装和除去的N-嘧啶基通过CH活化可完全控制C2区域。一系列吲哚底物经历了交叉脱氢-均偶联。这项工作开发了一种有效的方法,用于合成对材料和药物化学至关重要的许多化学物质的2,2'-联吲哚核。
