A highly enantioselective metal-free reduction of 3H-indoles has been developed. This Brønsted acid catalyzed transfer hydrogenation of indolederivatives with Hantzsch dihydropyridine as the hydrogen source constitutes an efficient method for the synthesis of various optically active indolines with high enantioselectivities.
