Abstract: Chiral phosphoric acid was found to be an effective organocatalyst in the enantioselective aza-Michael addition of aromatic amines to nitroolefins giving the corresponding β-nitroamine products in good yields (65%–95%) with moderate to good enantiomeric excesses (16%–70%). This study represents the first example of a chiral phosphoric acid catalyzed asymmetric aza-Michael addition reaction.

Key words: chiral phosphoric acid, aromatic amine, nitroolefin, aza-Michael addition
