Abstract

Catalytic oxidation of alkynes by using pyridine N-oxides as external oxidants has proven to be a powerful tool in organic synthesis, allowing the assembly of functionalized carbocycles and heterocycles in a remarkably efficient manner. Recent progress in this area is reviewed with emphasis on metal-free or nonnoble-metal-catalyzed oxidative cyclizations.
