Efficient preparation of 4-hydroxyquinolin-2(1 H)-one derivatives with silver-catalyzed carbon dioxide incorporation and intramolecular rearrangement
Although 4-hydroxyquinolin-2(1H)-one derivatives have attracted much attention due to their biological benefits, conventional reactions under harsh heat conditions must be employed to provide these key compounds. In the presence of a catalytic amount of s

The palladium-catalyzed transfer hydrogenation/heterocyclization of β- (2-aminophenyl)-α,β-ynones. An approach to 2-aryl- and 2-vinylquinolines
The palladium-catalyzed transfer hydrogenation/cyclization of readily available β-(o-aminophenyl)-α,β-ynones I affords 2-aryl- and 2- vinylquinolines 3 in good yield.
