An efficient synthetic route towards N-methylated or nonmethylated 3,4-dihydrocyclopent[b]indol-1(2H)-ones (3) and 1,2,3,9-tetrahydrocarbazol-4(4H)-one (10) was elaborated, based on Pd-catalyzed intramolecular Heck reaction. The chemoselectivity of the cyclization was studied in the case of the bi- and trifunctional substrates 12 and 17, respectively. In the latter case, depending on the catalyst, either the brominated indole 18 or the tetracyclic compound 19 were obtained by single and double Heck reaction, respectively.
Condensed Heteroaromatic Ring Systems; XVII: Palladium-Catalyzed Cyclization of β-(2-Halophenyl)amino Substituted α,β-Unsaturated Ketones and Esters to 2,3-Disubstituted Indoles

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.
