  • Title: Chiral HPLC separation and absolute configuration assignment of a series of new triazole compounds.
    Author: Lv C, Zhou Z.
    Journal: J Sep Sci; 2011 Feb; 34(4):363-70. PubMed ID: 21298778.
    Abstract:
    A series of novel chiral triazole compounds were synthesized. They were separated into enantiomers by liquid chromatography on an amylose tris(3,5-dimethylphenylcarbamate) (ADMPC) chiral stationary phase (CSP). The absolute configuration of each enantiomer of the investigated compounds was established by combined use of chemical correlation, chiral HPLC and circular dichroism (CD) spectra analysis methods. The influence of the mobile-phase modifiers and the structure of chiral triazole compounds on the chiral separation and retention were investigated. Reversal of the elution order of some enantiomeric pairs upon using different mobile-phase modifier was observed. The temperature effect on the chiral separation and the thermodynamic properties including enthalpy and entropy change of binding to the ADMPC-CSP were also investigated.
