The first direct general method for N-Me aziridination of electron-deficient olefins, enones, is described using N-methyl-O-tosylhydroxylamine as the aminating agent in the presence of a Cu(OTf)2 catalyst. The aziridination of vinyl ketones, hitherto unknown for N-Me as well as N-H, has been achieved efficiently. The open-flask reaction is stereospecific, operationally simple, and additive-free. It
描述了在Cu(OTf) 2催化剂存在下使用N-甲基-O-甲苯磺酰基羟胺作为胺化剂,对缺电子烯烃烯酮进行N -Me氮丙啶化的第一种直接通用方法。N -Me 和N -H迄今未知的乙烯基酮的氮丙啶化已有效实现。开瓶反应具有立体特异性、操作简单且无添加剂。它还在类似的反应条件下有效地提供了N -H 氮丙啶化产物。
