Cascade One-Pot Method To Synthesize Isoquinolin-1(2H)-ones with α-Bromo Ketones and Benzamides via Pd-catalyzed C–H Activation

摘要

A cross-coupling strategy of palladium-catalyzed ortho -C–H bond activation and intramolecular addition of N–C annulation to synthesize isoquinolin-1(2 H )-ones has been developed. A wide range of α-bromo ketones with different substituents proceeded smoothly in this reaction, and varieties of isoquinolin-1(2 H )-one derivatives were obtained in moderate to good yields.
