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

Abstract
Palladium-catalyzed cyclization of β-(2-halophenyl)amino substituted α,β-unsaturated ketones and esters, prepared from 2-haloanilines by three different methods, gave 2,3-disubstituted indoles.
