Preparative scale supercritical fluid chromatography was used to separate derivatized anomeric monosaccharides. Methyl 2,3,4,6-tetra-O-benzoyl-α-d-glucopyranoside and methyl 2,3,4,6-tetra-O-benzoyl-β-d-glucopyranoside were synthesized by benzoyl derivatization of the parent anomerically pure monosaccharides. The elution profiles of each anomer were studied, suggesting that separation was
