Intramolecular Cycloaddition Reactions of N-Sulfonyl Nitrile Imides Bearing Alkenyl Groups

The reaction of the p-tolyl(or phenyl)sulfonylhydrazones of some 2-(alkenyloxy)benzaldehydes with lead tetraacetate leads, via the nitrile imide intermediates, Ar-C(+)=N-N(-)-SO2-C6H4-X-p, to intramolecular 1,3-dipolar cycloadducts and 1-acetyl-2-aroyl-1-
