The pH was set at 7.9 with pure acetic acid. Samples were put in the SDS-agarose gel and the gels were run in a horizontal electrophoresis system (Mini-Sub Cell GT—7 10 cm (W x

Resolution of Racemic Mixtures 3 All methods for separating or characterizing enantiomers exploit the formation of diastereomeric interactions. Although the interactions that create diastereomers out of enantiomers are commonly: (i) Ionic interactions or (ii)Covalent interactions, However, this is not a strict requirement for separations.

b-cyclodextrine modified capillary electrophoresis is described. The distribution of enantiomers in clandestine tablets and urine samples were identified. Several electrophoretic parameters such as the concentration of b-cyclodextrin, temperature, the applied voltage and the amount of organic solvent required for successful separation were .

alyzed asymmetric epoxidation (AE) of allylic alcohols according to Sharpless. This process was applied to the synthesis of enantiomers of fluoxetine, using D or L enantiomers of diisopropyltartrate as ligands (Scheme 10) (14).
