Abstract

Three-dimensional nitrogen-containing heterocyclic compounds widely exist in many natural products and drugs. The dearomatization of N-heteroarenes and their derivatives have been recognized as one of the most important and powerful strategies for the rapid and efficient synthesis of various three-dimensional nitrogen-containing heterocyclic compounds. In this short review, the recent and representative advances in base-metal-catalyzed dearomatization of N-heteroarenes are summarized and discussed.
