| Abstract: | A newly developed reversed phase cellulose tris(4-methyl benzoate) known as Chiralcel OJ-R was used to investigate the chiral recognition and enantiomeric separation of eight racemic piperidine-2,6-dione compounds—namely, aminoglutethimide and its major metabolite acetylaminoglutethimide, glutethimide, cyclohexylamino-glutethimide, pyridoglutethimide, thalidomide, phenglutarimide, and 3-phenylacetyl-amino-2,6-piperidinedione (antineoplaston A-10). Chiral separation of these compounds was achieved under varying ratios of the mobile phase, except for phenglutarimide and 3-phenylacetylamino-2,6-piperidinedione, for which separation was unsuccessful. Possible chiral recognition mechanisms are also presented. Chirality 9:10–12, 1997. © 1997 Wiley-Liss, Inc. |
