Enantioselective separation of epoxides by capillary electrophoresis employing sulfated beta-cyclodextrin as chiral selector.
A capillary electrophoresis method was developed for the enantioseparation of epoxide compounds. Sulfated beta-cyclodextrin was employed as a chiral selector. Phosphate-triethanolamine buffer showed a chiral separation effect when employing charged sulfated beta-cyclodextrin. The effect of pH, triethanolamine concentration and sulfated beta-cyclodextrin concentration on the resolution was studied. Methanol was tested as an organic modifier. Several other epoxides were successfully separated by the proposed method.
