Coronands (3a) and (3b) derived from D-sorbitol display but poor or no recognition towards (R)- or (S)-α-phenylethylammonium hexafluorophosphates (PEA.HPF6) but selectively extract (R)- and (S)-enantiomers, respectively, of the α-phenylglycine methyl ester salt.All novel derivatives of D-mannitol (6, 7a-e) show no chiral recognition towards PEA.HPF6 or PEA.HClO4, the complexing ability of podands 7a-e varying with the nature of side chains.
