Abstract

Enantioselective reduction of 3-substituted quinolines has been achieved using a cyclopentadiene-based chiral Brønsted acid as catalyst and Hantzsch ester as hydrogen donor, affording the corresponding tetrahydroquinolines in good enantioselectivities.

Key words

tetrahydroquinolines - transfer hydrogenation - 3-substituted quinolones - enantioselectivity - chiral Brønsted acid
