Enantioselective hydrophobic entanglement of enantiomeric solutes with chiral functionalized micelles by electrokinetic chromatography

Enantiomeric Separations in Capillary Electrophoresis Using 18-Crown-6-tetracarboxylic Acid (18C6H4) as Buffer Additive

“…sodium dodecanoyl valinate [25] and N-dodecoxycarbonylvaline [26]). They are often mixed with non-chiral micelles e.g.…”

Discontinuous electrokinetic chromatography of parabens using different substituted resonances as pseudostationary phases

“…V al = X 1 V res + X 2 V eof (2) in which V res is the resorcarene velocity (with negative sign, as the resorcarenes move in anodic direction), X 1 is the molar fraction of the analyte interacting with resorcarenes, and X 2 is the molar fraction of the analyte in the free electrolyte, with X i = n i / n tot ; n i and n tot are the analyte amounts in ªphaseº i or the total amount, respectively.…”

Chiral separations in capillary electrophoresis

“…Derivatives of valine [131±133], alanine [131], cysteine [134] and proline [133] forming negatively charged micelles were synthesized and applied with success in the analysis of compounds of pharmaceutical interest. The same approach was applied in preparation of surfactants derived from (R,R)-tartaric acid [135] and with glucopyranoside-based surfactants bearing long alkyl chains with phosphate or sulfate as charged groups [136].…”
