New single isomer negatively charged β-cyclodextrin derivatives as chiral selectors in capillary electrophoresis.


To improve resolution power of chiral selector and enantiomeric peak efficiency in CE, single isomer negatively charged β-CD derivatives, mono(6-deoxy-6-sulfoethylthio)-β-CD (SET-β-CD) bearing one negative charge and mono[6-deoxy-6-(6-sulfooxy-5,5-bis-sulfooxymethyl)hexylthio]-β-CD (SMHT-β-CD) carrying three negative charges, were synthesized. The structure… (More)
