Abstract
The liquid chromatography enantiomeric separation of a series of 17 chiral sulfoxides was systematically investigated using multimodal elution with the new synthetic polymeric stationary phases P-CAP, P-CAP DP and DEAVB. The sulfoxide series was composed of aryl alkyl sulfoxides, benzoimidazole sulfoxides and the drugs modafinil, albendazole sulfoxide, omeprazole, lansoprazole, pantoprazole and rabeprazole. This work examines the effectiveness of the polymeric chiral stationary phases for the separation of chiral sulfoxides and describes the superiority of DEABV for these separations in three different elution modes. The first ever reversed phase enantiomeric separations on these columns is demonstrated.
