Synthesis of α-Aminonaphthalenes via Copper-Catalyzed Aminobenzannulation of (o-Alkynyl)arylketones with Amines

A copper-catalyzed aminobenzannulation of (o-alkynyl)arylketones with amines has been developed. This method features the use of a cheap copper catalyst, the facile annulation involving various amines, and the good functional group tolerance.
