Separation of binaphthyl enantiomers by capillary zone electrophoresis and electrokinetic chromatography

Abstract The capillary electrophoretic (CE) separation of the enantiomers of three binaphthyl compounds is investigated. Several CE modes such as cyclodextrin (CD) modified capillary zone electrophoresis (CZE) (CD‐CZE), micellar electrokinetic chromatography (MEKC), cyclodextrin electrokinetic chromatography (CD‐EKC), etc. are employed for the simultaneous enantiomer separation of the three solutes. The successful separation was achieved by combining two modes, in other words by using more than two chiral selectors. A development of the CE enantiomer separation is demonstrated for the binaphthyl compounds. The enantioselectivity of binaphthyl compounds is alo briefly discussed.
