Chiral recognition mechanisms of four β-blockers by HPLC with Amylose Chiral Stationary Phase
The high performance liquid chromatography (HPLC) enantioseparation of four β-blocking agents metoprolol, bisoprolol, propranolol and atenolol was performed on amylose tris-(3,5-dimethylphenylcarbamate) chiral stationary phase using n-hexane-ethanol-diethylamine (DEA) as the mobile phase and related chiral recognition mechanisms were discussed. Enantiomeric separation of the fourβ-blockers was ...

متن کاملHigh performance liquid chromatographic enantioseparation of chiral bridged polycyclic compounds on chiralcel OD-H and chiralpak OT(+).
The HPLC enantiomeric separation of 29 racemic bridged polycyclic compounds was examined on commercially available Chiralcel OD-H and Chiralpak OT(+) columns. The separations were evaluated under normal-phase mode (hexane containing mobile phase) for Chiralcel OD-H and under normal-phase as well as under reversed-phase mode (pure MeOH, temperature 5 degrees C) for Chiralpak OT(+). Almost all co...
متن کاملReview High-performance liquid chromatographic enantioseparation of drugs containing multiple chiral centers on chiral stationary phases
In recent years there has been considerable interest in the synthesis and separation of enantiomers of organic compounds especially because of their importance in the biochemistry and pharmaceutical industry. High-performance liquid Chromatography is a very useful method for the direct separation of enantiomers. However, about 30−40 years ago, commercially available chiral stationary phases wer...
متن کاملHigh-performance Liquid Chromatography Separation of Glycerol Derivatives on a Chiral Stationary Phase
We report herein the separation of enantiomers of glycerol derivatives on a cellulose-modified chiral column (Chiracel OD) in normal-phase mode. This method is suitable for monitoring the progress of the reaction and for determination of the enantiomeric purity of products. The lipase Novozyme 435-catalysed enantioselective hydrolysis of 1-O-benzyl-2,3di-O-octanoyl-rac-glycerol has been shown t...
