be an effective organocatalyst in the enantioselective aza-Michaeladdition of aromaticamines to nitroolefins giving the corresponding β-nitroamine products in good yields (65%-95%) with moderate to good enantiomeric excess (16%-70%). This study represents the first example of a chiral phosphoric acid catalyzed asymmetric aza-Michaeladdition reaction.
