The 1,3-dipolar cyclosddition reaction of pyrazolidinium ylide 1 vith substituted vinyl sulfones 5 warn studied. Elimination of benzeneaulfinic acid from the resulting cycloadducts gave rise to bicyclic pyrazolidiaones 3. The (E)-olefin isomers vere found to undergo cycloadditioo in a highly regiose
## Abstract magnified image The regioselectivity of the 1,3βdipolar cycloaddition of benzonitrile __N__βoxide to phenyl vinyl sulfoxide is established by isotopic labeling and ^13^C NMR analysis, and by DFT calculations. J. Heterocyclic Chem., (2009).
