This article may be used for non-commercial purposes in accordance with Thieme Terms and Conditions for self-archivingIndoles, dihydroisoquinolines and dihydroquinolines were efficiently prepared by ruthenium-catalyzed heterocyclizations of aromatic homo- and bis-homopropargyl amines/amides in the presence of an amine/ammonium base-acid pair. These regioselective 5- and 6-endo cyclizations most probably occur by nucleophilic trapping of key Ru vinylidene intermediates.eng© Georg Thieme Verlag Stuttgart · New York.
