Palladium-catalyzed intramolecular C-arylation of benzylic carbon: synthesis of 3-benzoxazolylisoindolinones by a sequence of Ugi-4CR/postfunctionalization.
Submitting Ugi-adduct 4 to two consecutive metal-catalyzed intramolecular reactions, namely copper-catalyzed O-arylation and palladium-catalyzed C-arylation of benzylic carbon developed in the course of this study, affords the benzoxazolylisoindolinones in good to excellent yields.
