Construction of 2‐Azabicyclo[2.2.1]heptenes via Selenium‐Catalyzed Intramolecular Oxidative Amination of Cyclopentenes

Abstract

AbstractA selenium‐catalyzed intramolecular oxidative amination of cyclopentenes has been described. A variety of 2‐azabicyclo[2.2.1]heptenes were obtained with 58%–96% yields. This protocol was featured with mild reaction conditions and broad substrate scope. The subsequent modification of the bicyclic backbone and amino group further demonstrated the application value of this aza‐bridged ring.
