Abstract

Ab stract Three new cinchona-type chiral selectors have been prepared by attaching N- pivaloyl-glycine, N-pivaloyl-(S)-valine and N-pivaloyl-(R)-valine segments to the C9-amino function of 9-amino-9-(deoxy)-epiquinine (eAQN), and immobilized to silica to provide the corresponding chiral stationary phases (CSPs). Evaluation of the chromatographic enantioseparation characteristics of these CSPs with a broad assortment of N-carbamoyl ...
