Condensed Heteroaromatic Ring Systems; XVII:1Palladium-Catalyzed Cyclization of β-(2-Halophenyl)amino Substituted α,β-Unsaturated Ketones and Esters to 2,3-Disubstituted Indoles

dihydropyridones bearing both C–N axis and point chirality were synthesized with good diastereo- and enantioselectivity under mild conditions. This efficient strategy successfully superpositions an extra point chiral element with an axial backbone, and the generated structurally interesting atropisomers may have potential application in drugdiscovery.
