as water compatible highly efficient organocatalysts for a direct enantioselective aldolreaction. A simple protonated (S)-prolinamide organocatalyst prepared from l-proline and 3-nitroaniline catalyzes the aldolreaction of unmodified ketones and a variety of aromatic aldehydes yielding aldol product in high yield with enantioselectivities of up to 98% and diastereoselectivity of up to >99:1.
