A new 4-unsubstituted monocyclic oxazolium-5-olate (7c) was generated and NMR-characterized. Several 3-alkyl- and 3-aryl-4-acylated monocyclic munchnone and sydnone derivatives were also prepared. From NMR experimental data and theoretical calculations di

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.
