A new class of acid-base chiral organocatalysts 1a and 2 for aza-Morita-Baylis-Hillman (aza-MBH) reaction of conjugated nitroalkenes is described. The acidic phenolic hydroxy groups and basic imidazole unit cooperatively activate nitroalkenes to promote the aza-MBH reaction in good yields with moderate enantioselectivities.
