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 .alpha.,.beta.-unsaturated carbonyl compounds such as .alpha.,.beta.-unsaturated ketones and .alpha.,.beta.-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.
