The reaction of 2<I>H</I>-1-benzopyran with several 1,3-dipoles gives cycloadducts in good yields. The orientation of the cycloaddition is qualitatively interpreted in terms of FMO theory. These heteropolycyclic compounds were also obtained from hydrazones of 3-aroyl-2<I>H</I>-1-benzopyrans, prepared from 3-cyano-2<I>H</I>-1-benzopyran.
