we report the regio- and chemoselectivereactions of indole with carbamoylelectrophiles in presence of AlMe3. Indole-3-carboxamide was prepared in one-step from a reaction of indole with tertiary carbamoylimidazole in the presence AlMe3. Under conditions for the formation of an aluminium ate complex, the reaction was diverted to the indole nitrogen. Secondary carbamoylelectrophiles in the presence

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
