  • Chiral imidazolidinone-based catalyst composition and reaction system
    Patent number: 6534434
    Abstract: Acid addition salts of imidazolidinones are provided as catalysts for transforming a functional group within a first reactant by reaction with a second reactant. Exemplary first reactants are &agr;,&bgr;-unsaturated carbonyl compounds such as &agr;,&bgr;-unsaturated ketones and &agr;,&bgr;-unsaturated aldehydes. Chiral imidazolidinone salts can be used to catalyze enantioselective reactions, such that a chiral product is obtained from a chiral or achiral starting material in enantiomerically pure form.
