Access to Aminated Saturated Oxygen Heterocycles via Copper-Catalyzed Aminooxygenation of Alkenes.

A copper-catalyzed aminooxygenation of unactivated alkenes with various O-nucleophiles is described. This novel methodology uses commercially available N-fluorobenzenesulfonimide as an amination reagent and provides a simple and efficient approach to a wide range of aminated saturated oxygen heterocycles in moderate to good yields. The reaction features mild reaction conditions, operational simplicity, and a broad substrate scope.
