An environmentally benign one-pot protocol has been developed for the syntheses of 3-alkyl/aryl-3-(pyrrole/indole-2/3-yl)-2-phenyl-2,3-dihydro-isoindolinones via a multi-component one-pot reaction involving 2-iodo-N-phenylbenzamides, terminal alkyne and substituted indoles/pyrroles in aqueous medium using cubic cuprous oxide nanoparticles as catalyst. It involves domino Sonogashira-5-exo-dig-cyclization followed by regioselective nucleophilic addition of indoles or pyrroles, in aqueous medium without using any surfactants or additional ligands.

henyl-2,3-dihydroisoindolinones via multicomponent one-pot reaction involving 2-iodo-N-phenylbenzamides, terminal alkyne, and substituted indoles in aqueous micellar medium. It involves copper-mediated domino Sonogashira-5-exo-dig-cyclization followed by regioselective nucleophilic addition of indoles, all in one-pot, using CuI as catalyst and 2,2′-(1E,1′E)-(1R,2R)-cyclohexane-1,2-diylbis(azan-1-y
