An efficient synthesis of 2-substituted benzoxazoles via copper acetate monohydrate oxidative coupling of aldehydes
with o-aminophenol is described. This synthetic strategy has some advantages as simple procedure, inexpensive
and easily available catalyst, and facile isolation of the products in moderate to good yields.
Keywords: Benzoxazoles, aromatic aldehydes, o-aminophenol, copper acetate monohydrate, oxidative cyclization.
