Title	Asymmetric Michael Reaction of Malonate Derivatives with α,β-Unsaturated Ketones Using Chiral Quaternary Ammonium Salts
Author	Min Je Cho, Myoung Gi Cho, Sun Chul Huh, Sung Min Kim, Kilsung Lee, Kwang Oh Koh, Joo Yang Mang, Dae Young Kim*
Keywords	Phase-transfer catalyst, Michael reactions, Asymmetric reactions, Malonates, Fluoromalonates
Abstract	The catalytic enantioselective Michael reaction promoted by quaternary ammonium salts from Cinchona alkaloids as a phase-transfer catalyst is described. Treatment of malonates with α,β-unsaturated ketones under mild reaction conditions afforded the corresponding Michael adducts in good yields with good to moderate enantiomeric excesses.
