Palladium-Catalyzed Intramolecular C-Arylation of Benzylic Carbon: Synthesis of 3-Benzoxazolylisoindolinones by a Sequence of Ugi-4CR/Postfunctionalization
Submitting Ugi-adduct to two consecutive metal-catalyzed intramol. reactions, namely copper-catalyzed O-arylation and palladium-catalyzed C-arylation of benzylic carbon developed in the course of this study, affords the benzoxazolylisoindolinones, e.g., I, in good to excellent yields.
