A nickel catalyzed acceptorless dehydrogenative approach to quinolines

A general, efficient and environmentally benign, one-step synthesis of substituted quinoline derivatives was achieved by acceptorless dehydrogenative coupling of o-aminobenzylalcohols with ketones and secondary alcohols catalyzed by a cheap, earth abundant and easy to prepare macrocyclic nickel catalyst [Ni(MeTAA)].
