The sulfinamidines as aza analogues of sulfinamides received limited attention from both organic chemists and pharmaceutical chemists. Herein, we present a tandem oxidative/nucleophilic substitution approach for the synthesis of sulfinamidines in high yield (up to 98%). This cascade reaction method is enabled by N-bromosuccinimide (NBS) as an oxidant and diverse readily available amines as nucleophiles
作为亚磺酰胺的氮杂类似物的亚磺胺受到有机化学家和药物化学家的有限关注。在此,我们提出了一种串联氧化/亲核取代方法,用于高产率(高达 98%)合成亚磺胺。这种级联反应方法由 N-溴代琥珀酰亚胺 (NBS) 作为氧化剂和多种易得的胺作为亲核试剂实现,无需任何添加剂或催化剂。值得注意的是,该方法非常省时、操作安全、易于放大,并且具有出色的功能组相容性。
