A novel copper‐catalyzed amination‐induced 1,2‐rearrangement reaction of allylic alcohols has been developed under simple and mild conditions. The commercially available N‐fluorobenzenesulfonimide (NFSI) is employed as an amination reagent. In this transformation, not only alkyl, but also aryl substituents can efficiently undergo 1,2‐carbon atom migration, thereby providing an efficient and powerful
在简单温和的条件下,已开发出一种新的铜催化的胺化引起的烯丙基醇的1,2-重排反应。使用市售的N-氟苯磺酰亚胺(NFSI)作为胺化试剂。在这种转化中,不仅烷基,而且芳基取代基都可以有效地经历1,2-碳原子迁移,从而为制备各种α-季曼尼希碱提供了有效而有力的途径。该反应具有广泛的底物范围,操作简单和优异的实用性。
