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.
