The separation of the enantiomers of phenylalanine amide and N‐methyl derivatives as well as some amino alcohols was studied by CE in acidic BGEs using CDs as chiral selectors. The native CDs displayed only low chiral recognition ability at a concentration of 15 mg/mL in 20 mM sodium phosphate buffer, pH 2.5. In contrast, the analyte enantiomers were separated in the presence of randomly sulfated...
Chiral recognition phenomena play an important role in nature as well as analytical separation sciences. In chromatography and capillary electrophoresis, enantiospecific interactions between a chiral selector and the enantiomers of an analyte resulting in transient diastereomeric complexes are required in order to achieve enantioseparations. The formation of the complexes is driven by ionic interactions,...
