An efficient and environmentally friendly process is reported for the palladium(II)‐catalyzed cyclofunctionalization of allylic hydroxylamine derivatives using oxygen as the cooxidant with only a catalytic amount of copper(II) acetate is reported. This method shows the environmentally benign process for the synthesis of isoxazolidine derivatives.
