Summary: The chiral stationary phase on the base of β-cyclodextrin and the mobile phase acetonitrile/0.1 mol/l
acetate buffer pH=5.2 (88/12 w/w) were used for the separation of the enantiomers of 1-methoxymethyl,
1-ethoxymethyl, 1-propoxymethyl-2-(1-pyrrolidinyl), (1-piperidino), (1-perhydroazepinyl)-
ethyl esters of 2-alkoxyphenylcarbamic acid. The influence of the structure of these compounds and
the influence of temperature on enantioseparation were studied. The dominant effect on the
resolution of enantiomers is exerted by the length of the alkoxysubstituent on the aromatic ring and
its position with regard to the stereogenic centre. A decrease in temperature caused an increase in
the retention factors of the compounds under study and the resolution values of enantiomers.
