Abstract

α-(Tosylhydrazono) phenylacetyl chloride and-Monosubstituted thioamides in dry, non-protic solvents and in the presence of EtN give representatives of the title mesoionic ring system in good to excellent yields; carbene or carbenoid type intermediates are most likely involved in these regiospecific cyclizations.
