Abstract
A chiral crown ether incorporating a methyl alpha-D-mannopyranoside un it displayed pronounced enantioselection of amino acids in partition l iquid chromatography experiments involving solvent systems of limited miscibility: water-ethanol-2,2,4-trimethylpentane. The same system has been used for amino acid transport across a liquid membrane containin g the crown ether, and in liquid-liquid extraction experiments. Remark able enantioselection has been noted for amino acids in all the proces ses studied.
