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

An efficient one-pot two-step sequential reaction for the synthesis of biologically active 3-hydroxyisoindolin-1-one derivatives from 2-iodobenzamide derivatives and various substituted benzyl cyanides in the presence of CuCl and cesium carbonate in DMSO is reported. Furthermore, 3-hydroxyisoindolinone derivatives possessing bromo substituents were obtained from 2-iodobenzamide and 2-bromobenzyl cyanide
