A novel copper-catalyzed direct C-N formation reaction of simplearenes with cheap and pharmacological saccharin derivatives under relatively mild conditions was developed with arenes as limiting reagents. This work provided a new method for oxidativecoupling of aromatic C(sp2)-H bonds and N-H bonds.
method for the synthesis of 2‐amino and β‐amino five‐membered heterocyclic derivatives that are closely related to a variety of biologically active natural products is described. Regioselectivity was achieved through a metalcatalytic or organocatalyticapproach. Preliminary studies on the reaction mechanism suggest a radical imidation pathway; however, further studies are needed to verify the mechanism
