A new synthetic route to indeno[1,2-b]quinolines via reactions of o-propargylbenzaldehydes with N-aryl amines based on an intramolecular aza-Diels-Alder (Povarov) reaction has been developed. This method offers several advantages such as no requirement for an oxidant, high efficiency, and a wide reaction scope.
