Abstract
A method of preparing cyclized derivatives of c-carboxybenzenesulfonic acid, characterized in that compounds according to one of the formulas ** (See formula) ** in which X is selected from the class consisting of hydrogen and the sulfamoyl group, R is selected from the class consisting of alkyl radicals and substituted or unsubstituted aryl, aralkyl, biphenylyl, cycloalkyl, and cycloalkylalkyl radicals, having up to 12 carbon atoms, and R1 is selected from the class consisting of hydrogen, alkyl, alkenyl, alkynyl, aralkyl, and keto-substituted alkyl and aralkyl radicals, containing up to 9 carbon atoms, are prepared by the reaction of a chloro-saccharin salt substituted or not substituted by sulphamoyl and a reactive ester of an alcohol HO-CH2-CO-R, in which R has the meaning defined above, with the aid of a condensing agent suitable, and followed, if desired, by conversion of the product obtained in the corresponding benzothiacinone, by means of an excess of sodium alcoholate, and followed, if necessary, by introduction of the group R1.
