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-catalyzedoxidative desulfurization-promoted intramolecularcyclization reactions of thioamides take place under neutral and mild conditions by using molecular oxygen as an oxidant. The proc...
