Palladium-Catalyzed Oxime Assisted Intramolecular Dioxygenation of Alkenes with 1 atm of Air as the Sole Oxidant

This paper describes a palladium-catalyzed oxime assisted intramolecular dioxygenation of alkenes by using 1 atm of air as the sole oxidant under extremely mild conditions, which demonstrated the feasibility of incorporating atmospheric oxygen into synthetically useful products under 1 atm of air at room temperature.
