A metal and additive-free stereospecific direct N-H and N-Me aziridination of inactivated olefins is disclosed using N-Boc-O-tosylhydroxylamine (TsONHBoc) as an aminating agent in hexafluoroisopropanol (HFIP). The use of TsONHBoc, which generates the free aminating agent in situ under the reaction conditions, has several inherent advantages over other similar agents, such as low cost, easy access
公开了在六氟异丙醇 (HFIP) 中使用N -Boc- O-甲苯磺酰基羟胺 ( TsONHBoc ) 作为胺化剂,对灭活烯烃进行无金属和无添加剂的直接N - H 和N -Me 氮丙啶化。使用在反应条件下原位生成游离胺化剂的 TsONHBoc与其他类似试剂相比具有几个固有的优势,例如成本低、易于获取以及在较长时间内储存期间的稳定性(非爆炸性)。
