We present enantioseparation of a series of racemic sulfoxides on three different amylose-based polysaccharide columns. Two of them have the amylose units modified with dimethylphenyl carbamoyl groups (Chiralpak AD-H and Chiralpak IA), while the third one possesses a carbamoyl moiety with an additional chiral centre (Chiralpak AS-H). The enantioseparation of selected analytes was achieved in high-performance liquid chromatography (HPLC) and the full analyte set was enantiomerically resolved using supercritical fluid chromatography (SFC). Comparing the results obtained in both modes, we show that enantioseparation under SFC conditions is superior to HPLC mode in terms of speed, while retaining excellent enantioselectivity and resolution. Faster elution of analytes was observed on increasing the polarity of the co-solvent (modifier) in the mobile phase. This trend is apparent in both chromatographic modes. Documenting the important role of the additional chiral centre, Chiralpak AS-H provided the best chromatographic parameters resulting in the enantioseparation of all analytes.
