Notes:
Capillary electrophoresis was used to separate diastereomers and enantiomers of synthesized thiopyrans and thiinopyrroles. Separation conditions were optimized by varying the buffer parameters, i.e., kind and concentration of chiral selector, pH, main buffering component, micelle forming additives, and content of organic solvents. The interaction of thiopyrans and thiinopyrroles with β- and γ-cyclodextrins results in the separation of enantiomers and diastereomers. The magnitude of the resolution depends on the spatial requirements of the different substituents of the analytes and the dimensions of the cyclodextrin cavity. For well-separated enantiomers or diastereomers the identification and characterization of degradation products was possible.
