Enantioseparation of chiral sulfoxides and sulfinate esters by capillary electrophoresis.
Forty-one chiral sulfoxides and sulfinate esters were separated using sulfated beta-cyclodextrin and carboxymethyl beta-cyclodextrin as chiral selectors. Binding constants of some analytes to both chiral selectors were measured in order to examine and help explain the observed migration behavior and enantioselectivity trends. Overall, sulfated beta-cyclodextrin separated a greater number of com...
متن کاملReagent controlled addition of chiral sulfur ylides to chiral aldehydes
The degree of reagent and substrate control in the reaction of chiral sulfur ylides with chiral aldehydes has been investigated. Specifically, the reactions of the two enantiomers of the chiral benzyl sulfonium salt 1 with glyceraldehyde acetonide were studied in detail. Of the two new stereogenic centers created, it was found that the C1 stereochemistry was largely controlled by the reagent, w...
متن کاملChiral nematic organo-siloxane oligopodes based on an axially chiral binaphthalene core.
The synthesis of a novel class of organosiloxane oligopodes, based on an axially chiral binaphthalene core is described and their mesogenic properties are fully characterised.
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 کاملChiral 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 ...
