Palladium-Catalyzed Intramolecular C-Arylation of Benzylic Carbon: Synthesis of 3-Benzoxazolylisoindolinones by a Sequence of Ugi-4CR/Postfunctionalization
摘要:
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 benzox-azolylisoindolinones in good to excellent yields.
