The enzyme 4-oxalocrotonate tautomerase (4-OT) promiscuously catalyzes the Michael-type addition of acetaldehyde to β-nitrostyrene derivatives to yield chiral γ-nitroaldehydes, which are important precursors for pharmaceutically active γ-aminobutyric acid

A novel category of diarylprolinol silyl ether catalysts which contain different lengths of alkylamine tags, was designed and synthesized. These catalysts were used, along with benzoic acid as the co-catalyst, to catalyze the asymmetric Michael reaction of the highly reactive acetaldehyde with nitroolefins. For the reactions studied, this catalytic system exhibited high reactivity in brine without any organic solvents; good yields (30-61%) and high enantioselectivities (80-97% ee) for a wide variety of nitrostyrenes were obtained.
