The dipolar cycloadditions of ortho-nitrophenyl alkynes with aryl nitrileoxides has been demonstrated. A range of substituents are tolerated on the alkyne. These reactions proceed with excellent levels of regioselectivity. Subsequent functionalization of the isoxazole scaffold has been demonstrated.
