    • PROBLEM TO BE SOLVED: To provide a method for producing an optically active compound, making use of an ionic nucleophilic catalytic action of an optically active ammonium betaine based on the nucleophilicity of the anionic part thereof. SOLUTION: The method for producing an optically active compound employs an ammonium betaine represented by formula (I) and an optical isomer thereof as an ionic nucleophilic catalyst [in formula (1), R 1 and R 2 may be the same or different and each represents at least one species of a hydrogen atom, a halogen atom, an alkyl group, an aryl group or an aryl group containing a substituent; R 3 represents a hydrogen atom, a halogen atom, an alkyl group, an aryl group, an alkoxyl group, an acyl group, an alkoxycarbonyl group or a sulfonyl group; and Me represents a methyl group].
