oxide, and chemoselective 1,3-dipolar cycloaddition reactions between in situ generated nitrile oxide and different alkynes are reported. The nitroalkane-mediated nitrile oxide–alkyne cycloaddition was found to be orthogonal to the copper(I)-catalyzed azide–alkyne cycloaddition reaction. The combination of orthogonal nitrile oxide–alkyne and azide–alkyne cycloaddition reactions can be explored to tailor
