Exceptional chiral recognition of racemic carboxylic acids by calix[4]arenes bearing optically pure alpha,beta-amino alcohol groups.
Calixarenes bearing optically pure alpha,beta-amino alcohol groups at their lower rim exhibit exceptional and efficient chiral recognition ability in discrimination of racemic mandelic acid, 2,3-dibenzoyltartaric acid and 2-hydroxy-3-methylbutyric acid. [structure: see text]
