Simple, rapid, and clean condensation of sulfonamide and maleic anhydride derivatives: Synthesis of novel 1<i>H</i>- Pyrrole-2,5-diones under heterogeneous conditions
GRAPHICAL ABSTRACT ABSTRACT H6P2W18O62 is used as an efficient catalyst for the synthesis of novel N-substituted sulfonyl maleimides (1H-Pyrrole-2,5-diones) via the condensation of sulfonamide and maleic anhydride derivatives. The Dawson heteropolyacid was used with a catalytic amount of 2 mmol% in acetonitrile at reflux. The reuse of H6P2W18O62 as heterogeneous catalyst several times without decrease
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.
