A novel synthetic strategy based on the intramolecularpalladium-catalyzed oxidative cyclization reaction, allows the formation of C–C bond and the synthesis of β-carbolinones. The reaction has been performed in the presence of catalytic amount of PdCl2(CH3CN)2 and benzoquinone as a reoxidant.

Intramolecular oxidative palladium‐catalyzed reactions of indolylallylamides in the presence of the couple bis(acetonitrile) palladium dichloride and copper(II) halide are described. Starting from 2‐ and 3‐indolylallylamides and involving in both cases the C‐3 position of the indole nucleus, variously substituted β‐carbolinones were obtained by arylation/halogenation, arylation/esterification or a
