Organocatalytic asymmetric intramolecular aza-Henry reaction: Facile synthesis of trans-2,3-disubstituted tetrahydroquinolines

Maity, Rajendra,Pan, Subhas Chandra

, p. 6825 - 6831 (2015)

An enantio- and diastereoselective organocatalytic intramolecular aza-Henry (nitro-Mannich) reaction has been developed. The trans-2-aryl-3-nitro-tetrahydroquinoline products are obtained in high yields and in good enantioselectivities with a bifunctional
