Using four β-cyclodextrin derivatives, 2, 6-di-O-benzyl-3-O-heptanonyl-β-CD, 2, 6-di-O-benzyl-3-O-octanonyl-β-CD, 2, 3-di-O-benzyl-6-O-heptanonyl-β-CD, and 2, 3-di-O-benzy1-6-O-octanonyl-β-CD, as chiral stationary phases of capillary gas chromatography (CGC), the enantiomers of Sharpless epoxides were well separated. The enantiomer excess values (e.e.%) of some chiral Sharpless epoxides were also determined successfully using these CDs.
