Abstract

A Cu(i)-catalyzed cross-coupling of primary amines with 2,2'-dibromo-1,1'-biphenyl for the synthesis of polysubstituted carbazole has been achieved. This protocol provides an efficient strategy for the synthesis of carbazole using cheap copper catalysts with diamine ligand, and it provides convenient access to a series of carbazole derivatives in moderate yields.

摘要

实现了一种铜（I）催化的伯胺与2,2'-二溴-1,1'-联苯的交叉偶联反应，用于合成多取代咔唑。该方法为使用廉价的铜催化剂和二胺配体合成咔唑提供了一种有效策略，并且能够以中等产率方便地获得一系列咔唑衍生物。
