title: Efficient resolution of racemic 1,1'-bi-2-naphthol with chiral selectors identified from a small library.
abstract: Efficient resolution of racemic 1,1'-bi-2-naphthol, a well-studied analyte in chiral separation, was achieved using selectors developed from a small library. Separation factors (up to 7.2) obtained are significantly higher than the ones reported previously for this analyte. The library consists of 121 members and it does not contain the pi deficient 3,5-dinitrobenzoyl (Dnb) group. These highly efficient stationary phases may lead to the practical large-scale chromatographic resolution of enantiomers of 1,1'-bi-2-naphthol, which are widely used as chiral auxiliaries and ligands in asymmetric synthesis.
