SIMPLE EVALUATION OF ENANTIOMER-SELECTIVITY OF CROWN ETHER USING MEMBRANE ELECTRODE

Abstract

Abstract Enantiomer-selectivity of the crown ethers I through IV was evaluated by a membrane electrode method. Only chiral crown ether II showed some enantiomer-selectivity for both hydrochloride salts of phenylalanine methylester and phenylethylamine. This method was considered to be a convenient one for screening the enantiomer-selectivity of chiral crown ethers.
