A convenient method for the "in column" synthesis of chiral stationary phases for high-performance liquid chromatography was elaborated. It involves preparation of chiral amides of 2-bromo- or 4-chloro-substituted 3,5-dinitrobenzoic acids followed by nucleophilic substitution of the halogen in the aromatic

Direct liquid chromatographic separations of the enantiomers of metoprolol and bisoprolol have been developed, using (R)-1-naphthylglycine and 3,5-dinitrobenzoic acid as chiral stationary phase (CSP). The separations were achieved in a normal phase system employing a mobile phase containing n-hexane, 1,2-dichloroethane
