Indirect resolution of beta-blocker agents by reversed-phase capillary electrochromatography.

Zeineb Aturki et al.

Electrophoresis, 25(4-5), 607-614 (2004-02-26)

The indirect resolution of five beta-adrenoreceptor blocking agents (propranolol, oxprenolol, pindolol, metoprolol, and atenolol) using precolumn derivatization with (+)-1-(9-fluorenyl)ethyl chloroformate (FLEC), and capillary electrochromatography (CEC) is reported. Three octadecylsilanized (ODS) silica gel-based stationary phases, differing in particle diameter and carbon

Liquid chromatographic analysis of propranolol enantiomers in human blood using precolumn derivatization with (+)-1-(9-fluorenyl)ethyl chloroformate.

A Roux et al.

Journal of chromatography, 570(2), 453-461 (1991-10-04)

A method for the determination of the R-(+) and S-(-) enantiomers of propranolol in blood was developed. After extraction with heptane-isopentanol and derivatization with (+)-1-(9-fluorenyl)ethyl chloroformate, excess reagent was removed using solid-phase extraction. The enantiomers were separated on an achiral

(+)-Fluorenylethylchloroformate (FLEC)--improved synthesis for application in chiral analysis and peptidomimetic synthesis.

Michelle A Camerino et al.

Organic & biomolecular chemistry, 11(16), 2571-2573 (2013-03-14)

An efficient synthesis of the enantiomers of fluorenylethylchloroformate (FLEC) has been achieved that allows the routine application of the reagent for the resolution of chiral amines including unusual amino acids. The utility of the fluorenylethoxycarbonyl (Feoc) group as a chiral
