    Abstract: 3,4-Dihydro-1,2,3-oxathiazinones, a class of chemical compounds having a ring system, are obtained by converting the enolether of a Beta -ketocarboxylic acid amide-N-sulfone to the enol and treating the enol with an aqueous base. The compounds and their salts are artificial sweetening agents. All of the compounds are organic intermediates having a plurality of reactive groups.
