NBS‐Promoted C−H Amination of Enaminones for the Synthesis of N‐Heterocycle Substituted Enaminones**

Abstract

Abstract A NBS‐promoted C−H amination of enaminones has been developed with a variety of N‐heterocycles. This methodology is highly practical as it employs inexpensive and simple NBS promotor under aerobic conditions without the additions of any transition metal catalyst. The transformation proceeds by the initial bromination of enaminones and the subsequent intermolecular substitution with N‐nucleophile to form C−N bond.
