Abstract

A highly efficient amidation reaction of heterocycles with N-fluorobenzenesulfonimide (NFSI) has been developed, presumably proceeding via C-H bond activation. Cuprous iodide was employed as the catalyst, and various α-amidated heterocycle derivatives have been generated in good to excellent yields. This chemistry endowed an economic method of synthesis of valuable amidated heterocycles through a direct C-N bond-coupling processes.
