Copper-Catalyzed Intermolecular Dehydrogenative Amidation/Amination of Quinoline <i>N</i>-Oxides with Lactams/Cyclamines

Abstract

C-H, N-H dehydrogenative coupling of quinoline N-oxides with lactams/cyclamines has been achieved in the presence of the Cu(OAc)2 catalyst to give good to excellent yields. This study provides a new strategy for the construction of a 2-aminoquinoline skeleton via direct functionalization of aryl C-H bonds.
