Recent Advances in Copper-Catalyzed N-O Cleavage Strategy

N-O bond cleavage is one of the most efficient and powerful strategies to introduce N- or O-functional groups into molecules in organic synthesis. Copper catalyst, as the abundant in earth and inexpensive advantages has been widely used to construct C-N and C-O bond. Furthermore, N-O bond cleavage has been successfully applied in the total synthesis of natural products and pharmaceuticals. The new development of copper-catalyzed N-O bond cleavage and its application in the total synthesis of natural products and pharmaceuticals in recent years have been summarized.
