methods are devoted to their activated counterparts. Herein, we have developed a highly efficient Rh(II)-catalyzed method for the direct preparation of unactivated aziridines from olefins using O-(sulfonyl)hydroxylamines as the aminating agent. The reactions proceed with a high stereospecificity.
未活化的氮丙啶是许多生物活性天然产物的核心亚结构,并充当有机合成的基础。尽管如此,由于大多数已知的方法都专门用于它们的活化对应物,因此可使用非常有限的方法直接从烯烃中获得它们。本文中,我们开发了一种高效的Rh(II)催化方法,可使用O-(磺酰基)羟胺作为胺化剂直接从烯烃制备未活化的氮丙啶。反应以高立体特异性进行。
