dc.description.abstractPyridine-based macrocycles were prepared by treating 2,6-bis[[2'6'-bis(bromomethyl)-4'-methylphenoxy]methyl]pyridine 3 with the appropriate chiral aminoalcohols. The enantiomeric recognition of these macrocycles bearing aminoalcohol subunits of the pyridinocrown type ligand was evaluated for chiral organic ammonium salts by UV titration. The important differences were observed in the K-a values of (R)-Am2 and (S)-Am2 for (S,S,S)-1, (S,SS)-2 and (S,S,S)-3 hosts, K-S/K-R = 5.0, K-S/K-R = 2.4 and K-S/K-R = 5.0. respectively. There seems to be a general tendency for hosts to recognise (S)-enantiomers for both Am1 and Am2. (C) 2009 Elsevier Ltd. All rights reserved.en_US
