Abstract

Heptakis[2,3-di-O-methyl-6-O-(L-valine-tert-butylamide-Nα- ylcarbonylmethyl)]-β-cyclodextrin with methyl groups on the secondary sites and a diamide chiral selector on the primary ones showed considerable utility as a CSA in the NMR enantiodiscrimination of a wide spectrum of amino acid derivatives, while also allowing trisubstituted allenes to be enantiodiscriminated. Enantiodiscrimination processes were investigated by Diffusion-Ordered SpectroscopY (DOSY).
