Enantioseparation of basic chiral compounds on a clindamycin phosphate-silica/zirconia hybrid monolith by capillary electrochromatography.
An organic-inorganic silica/zirconia hybrid monolithic capillary column was prepared by sol-gel process in a fused-silica capillary by using triethoxysilylpropylcarbamate (TEOSPC) derivative of… Expand
HPLC enantioresolution of (R,S)-baclofen using three newly synthesized dichloro-s-triazine reagents having amines and five others having amino acids as chiral auxiliaries.
Enantioresolution of (R,S)-baclofen was accomplished using a newly synthesized set of three chiral derivatizing reagents (CDRs) having amines [(S)-(-)-α,4-dimethylbenzylamine, (-)-cis-myrtanylamine… Expand
Application of antibiotics as chiral selectors for capillary electrophoretic enantioseparation of pharmaceuticals: a review.
Recent years have witnessed several new trends in chiral separation, for example, the enantiorecognition ability of several new antibiotics has been explored using capillary electrophoresis (CE)… Expand
Reversed-phase high-performance liquid chromatographic separation of diastereomers of (R,S)-mexiletine prepared by microwave irradiation with four new chiral derivatizing reagents based on…
A new series of chiral derivatizing reagents (CDRs) consisting of four dichloro-s-triazine reagents was synthesized by nucleophilic substitution of one chlorine atom in trichloro-s-triazine with… Expand
Microwave-assisted synthesis and reversed-phase high-performance liquid chromatographic separation of diastereomers of (R,S)-baclofen using ten chiral derivatizing reagents designed from…
Four dichloro-s-triazine (DCT) and five monochloro-s-triazine (MCT) chiral derivatizing reagents (CDRs) were synthesized by incorporating amino acid amide moieties as chiral auxiliaries in… Expand
Amino acids as chiral selectors in enantioresolution by liquid chromatography.
Amino acids are unique in terms of their structural features and multidimensional uses. With their simple structures and the ready availability of both enantiomers, amino acids not only serve as a… Expand
Penicillin G as a novel chiral selector in capillary electrophoresis.
The penicillin sub-class of β-lactam antibiotics has not been examined for its enantiodiscriminating abilities in capillary electrophoresis (CE) until date. The present work was therefore designed to… Expand
Application of Hydrazino Dinitrophenyl-Amino Acids as Chiral Derivatizing Reagents for Liquid Chromatographic Enantioresolution of Carbonyl Compounds
A new series of chiral derivatizing reagents (CDRs) consisting of five hydrazino dinitrophenyl (HDNP)-amino acids (CDR 1–5) was prepared by a two-step synthesis procedure starting from… Expand
Enantioresolution of five β-blockers by reversed-phase high-performance liquid chromatography using fifteen chiral derivatizing reagents having amino acids or their amides as chiral auxiliaries on a…
Enantioseparation of five β-blockers, namely, (R,S)-atenolol, (R,S)-propranolol, (R,S)-bisoprolol, (R,S)-metoprolol and (R,S)-carvedilol, was achieved as their diastereomers prepared with chiral… Expand
Enantioseparation of basic chiral drugs on a carbamoylated erythromycin-zirconia hybrid monolith using capillary electrochromatography.
An organic-inorganic hybrid monolithic column was prepared within the confines of a capillary via a single-step in situ sol-gel approach using zirconium tetrabutoxide as a precursor to compose the… Expand
