reactivity and lead to distinct bond-forming modes. Herein we describe a rarely studied cycloaddition between nitrileoxides and electron-rich alkynes with reversed regioselectivity, leading to the useful 4-heterosubstituted isoxazoles. The use of a ruthenium catalyst completely overrides the inherent polarity of nitrileoxides. This reversed regioselectivity was also observed for their reactions with a range
