Abstract

Résumé/Abstract Chiral receptors [(S, S)-1] and [(S, S, S, S)-2] having 1, 2-dialkoxy-1-(3, 5- dimethylphenyl) ethane and 1, 2-dialkoxy-1-(3, 5-dimethyl phenyl) cyclohexane as chiral building blocks, respectively, were prepared. Thermodynamic parameters of complexations of these and structurally related receptors [(S, S)-3] and [(S, S, S, S)-4] with 2-amino-1- propanol (5), 2-amino-2-phenylethanol (6), and 3-methylbutan-1-ol (7) in chloroform were ...
