Capillary electrophoresis (CE) allows the observation of the opposite affinities of the enantiomers of (Β±)-verapamil [2-isopropyl-2,8-bis(3,4-dimethoxyphenyl)-6-methyl-6-azaoctannitrile, VP] toward β€-cyclodextrin (β€-CD) and heptakis(2,3,6-tri-Omethyl)-β€-CD (TM-β€-CD). In addition, in the presence of

Chiral Recognition of Amino Alcohols by 1 H and 13 C NMR Spectroscopy Using Binaphthyl Derivatives as Chiral Solvating Agents. -Different signals in the spectra are doubled in dependence on the substrate as well as the agent. In the 1 H NMR spectra mainly the CH 3 N signal is a useful indicator in
Benzoylated and benzylated cyclodextrins give rise to non-spectroscopy. Cyclodextrins bearing aromatic substituents at the primary or secondary sites only are more efficient CSAs equivalence in the 1 H-NMR spectra of racemates of 3,5dinitrophenyl derivatives of chiral amines, amino alcohols, compare
Capillary electrophoretic enantioseparation of compounds containing vicinal diol groups have been investigated using different β€-cyclodextrin (CD) derivatives and borate as a background electrolyte. Both native β€-CD and several β€-CD derivatives are examined. Chiral recognition is attributed to both
