Direct enantioselective hydrogenation of unsaturated compounds to generate chiral three-dimensional motifs is one of the most straightforward and important approaches in synthetic chemistry. We realized the Ru(II)-NHC-catalyzed asymmetric hydrogenation of 2-quinolones under mild reaction conditions. Alkyl-, aryl- and halogen-substituted optically active dihydro-2-quinolones were obtained in high yields with moderate to excellent enantioselectivities. The reaction provides an efficient and atom-economic pathway to construct simple chiral 3,4-dihydro-2-quinolones. The desired products could be further reduced to tetrahydroquinolines and octahydroquinolones.

Palladium-catalyzed oxidative cyclocarbonylation of N-monosubstituted-2- vinylanilines constitutes a simple, direct, and selective method for the synthesis of 2(1H)-quinolinones. The reaction conditions are attractive in terms of environmental considerations and operational simplicity. 2(1H)-Quinolinones with a variety of functional groups were prepared in up to 97% yield.
