Carbonylation reactions have been widely used in organic synthesis. However, the manipulation of toxic and pressurized carbonmonoxide limited their applications in organic laboratories. The search for alternative carbonyl sources as an important method for carbonylative organic synthesis is spreading. Herein, a series of substituted benzoxazinones were synthesized from N-(o-bromoaryl)amides by palladium-catalyzed
A one step synthesis of functionlized N-acylanthranilamidevia Pd-catalyzed carboxamidation of o-halo substituted N-phenylamide consisting of isocyanideinsertion followed by oxidation of the imine intermediate has been achived successfully. Furthermore, at elevated temprature (160oC) the Pd-catalyzed tandem reaction afforded functionlized quinazolin-4-one in a single step without the isolation of
