A palladium-catalyzed tandem addition/cyclization of 2-(2-aminoaryl)acetonitriles with arylboronic acids provides indole skeletons with good functional group tolerance and remarkable chemoselectivity. In particular, halogen substituents are amenable to further synthetic elaborations thereby broadening the diversity of the products. This transformation involves sequential nucleophilic addition followed by an intramolecular cyclization.
