GRAPHICAL ABSTRACT

Abstract

The synthesis of new series of pyrrolidine-2,5-diones having sulfonamide moieties is described. These compounds are synthesized in good yield in three steps (carbamoylation-sulfamoylation, deprotection and condensation) using a catalytic amount of H6P2W18O62 in acetonitrile under refluxing conditions.
