The phenyl ring of 3-(4-hydrazinocarbonylphenyl)sydnone activates a hydrazinocarbonyl group to undergo a series of reactions for preparing heterocyclic compounds including oxadiazoles, dihydropyrroles, and pyrroles. However, the hydrazinocarbonyl group on the C(4)-CH2 resists a cyclization under the same reaction conditions.

Treatment of 3-aryl-4-(1-hydroxyethyl)sydnones with DMSO-Ac2O yielded esters and ketones, depending on the amount of Ac2O used; application of a limited amount of Ac2O with DMSO as an oxidant has been found to be the only method to convert the title compounds to the ketones.
