Abstract

A solvent-controlled divergent thiocyanation of carbazoles and di/triphenylamines has been developed. Using either CH3CN/H2O (3:1) or DMSO as the solvent, a facile and efficient protocol for the solvent-controlled divergent synthesis of mono- and di-thiocyanation of carbazoles and di/triphenylamines was achieved. The salient features of this transformation include simple and mild reaction conditions, easily available substrates, and broad substrate scope.

硫氰酸咔唑和二/三苯基胺的溶剂控制分歧合成
开发了一种咔唑和二/三苯基胺的溶剂控制发散硫氰酸化方法。使用 CH3CN/H2O (3:1) 或 DMSO 作为溶剂,实现了咔唑和二/三苯基胺的单硫氰酸化和二硫氰酸化的溶剂控制发散合成的简便高效的方案。这种转化的显著特点包括反应条件简单温和、底物容易获得以及底物范围广泛。
