Use of electrostatic interaction for chiral recognition. Enantioselective complexation of anionic binaphthyls with protonated amino-?-cyclodextrin

Abstract

The studies using NMR and capillary zone electrophoresis clearly reveal that protonated 6A-amino- 6A-deoxy-β-cyclodextrin recognizes the chirality of anionic binaphthyl derivatives such as 1,1′-binaphthyl-2,2′-diyl phosphate and 1,1′-binaphthyl-2,2′-dicarboxylate through electrostatic interaction between the host and the guest and simultaneous inclusion.
