The catalytic enantioselective Michael reaction promoted by quaternaryammonium salt from cinchonidine as a phase transfer catalyst is described. Treatment of nitroalkanes with chalcone derivatives under mild reaction conditions afforded the corresponding Michael adducts in good yields with good to moderate enantiomeric excesses.
