Herein, we describe an efficient copper-catalyzed coupling of sulfonamides with alkylamines to synthesize (E)-N-sulfonylformamidines. The reaction is accomplished under mild conditions without the use of a corrosive acid or base as an additive. It tolerates a broad scope of substrates and generates the products with exclusive (E)-stereoselectivity.
在本文中,我们描述了磺酰胺与烷基胺的有效铜催化偶联以合成(E)-N-磺酰基甲am。该反应在温和条件下完成,无需使用腐蚀性酸或碱作为添加剂。它可以承受广泛范围的底物,并生成具有独特的(E)-立体选择性的产品。
