Copper(II)-Mediated Chelation-Assisted Regioselective N-Naphthylation of Indoles, Pyrazoles and Pyrrole through Dehydrogenative Cross-Coupling.

Abstract

A copper-mediated picolinamide directed regioselective cross-coupling of naphthylamines with azoles is developed via C-H functionalization and C-N bond formation. The reaction of indoles leads to the formation of chiral C-N cross-coupled products with functional group tolerance. These reaction conditions can also be extended to the cross-coupling of pyrazole and pyrrole scaffolds.
