Copper-catalyzed oxidative desulfurization-promoted intramolecular cyclization of thioamides using molecular oxygen as an oxidant: An efficient route to five- to seven-membered nitrogen-containing heterocycles

Copper-catalyzed oxidative desulfurization-promoted intramolecular cyclization reactions of thioamides take place under neutral and mild conditions by using molecular oxygen as an oxidant. The process yields a wide variety of nitrogen-containing heterocycles with high efficiency.
