Abstract

The N-benzylation of NH-sulfoximines via visible light photocatalysis is realized. Under mild reaction condition, photocatalyst promotes the direct cross coupling of NH-sulfoximines with benzyl bromide to form N-benzylation sulfoximines. Superbases which are usually used in reported coupling of NH-sulfoximines with alkyl halides are not needed in this work. This method is also suitable for the synthesis of N-allyl sulfoximines.

NH-亚砜肟的光催化N-苄基化

摘要

通过可见光光催化实现了NH-亚磺酰亚胺的N-苄基化。下温和的反应条件下，光催化剂促进的直接交叉偶联NH与苄基溴-sulfoximines以形成Ñ -benzylation亚磺酰亚胺。这项工作不需要通常用于报道的NH-磺胺嘧啶与烷基卤的偶合的超强碱。该方法也适合于合成N-烯丙基硫代亚砜。
