3-Acetylisoxazoles were synthesized by the reaction of alkenes or alkynes in acetone as solvent with copper(II) nitrate and formic acid. In the case of ethyl acetate as solvent, 3-benzoylisoxazoles were yielded by the reaction of alkynes and acetophenone with copper(II) nitrate and nitric acid. This synthetic method provides a convenient production of isoxazole derivatives.
