ONE-POT HIGHLY DIASTEREO-SELECTIVE SYNTHESIS OF NEW 2-SUBSTITUTED 8-(SPRIO-3′- INDOLINO-2′-ONE)-PYRROLO[3,4-a]-PYRROLIZINE-1,3-DIONES MEDIATED BY AZOMETHINE YLIDE INDUCED BY MICROWAVE IRRADIATION

Abstract

Isatin derivatives react with proline and N-Aryl Maleimides via decarboxylative azomethine ylide formation and subsequent 1,3-dipolar cycloaddition involving an exo-transition state to give new heterocyclic adducts in 71–94% yield.
