1,3‐Dipolar cycloaddition reactions of benzonitrileoxide to monosubstituted or 1,1‐disubstituted alkenyl boronic ester gave only 2‐isoxazolines, bearing the boronic ester group at the 5‐position of the ring. On the other hand, the cycloaddition reactions of benzonitrileoxide with trans‐1,2‐disubstituted alkenyl boronic esters produced 2‐isoxazolines, bearing the boronic ester group at the 4‐position
