Enantiomeric separation of homocysteine and cysteine by electrokinetic chromatography using mixtures of γ-cyclodextrin and carnitine-based ionic liquids
M Greno, M Castro-Puyana, ML Marina - Microchemical Journal, 2020 - Elsevier
Two new chiral ionic liquids based on the ester of the non-protein amino acid carnitine as
cationic counterpart were synthesized, characterized and evaluated as chiral selectors for
the enantiomeric separation of homocysteine and cysteine derivatized with 9-
fluorenylmethoxycarbonyl chloride by electrokinetic chromatography. The use of both ionic
liquids, l-carnitine methyl ester bis (trifluoromethane) sulfonimide and l-carnitine methyl ester
l-(+)-lactate, as sole chiral selectors in the separation buffer, did not allow the enantiomeric …
