Abstract: 2,3-Epoxypropyl 2,3,4,6-tetra-O-acetyl-β-D-glucopyranoside was obtained by oxidation of allyl 2,3,4,6-tetra-O-acetyl-β-D-glucopyranoside; deacetylation of the former compound afforded 2,3-epoxypropylacetyl-β-D-glucopyranoside, Analogous oxidation and deacetylation of allyl 2,3,4,6-tetra-O-acetyl-β-D-glucopyranosyl-(1→4)-2,3,6-tri-O-acetyl-β-D-glucopyranoside produced 2,3-epoxypropyl 2,3,4,6-tetra- O-acetyl-β-D-glucopyranosyl-(1→4)-2,3,6-O-acetyl-β-D-glucopyranoside and 2,3-epoxypropyl β-D-glucopyranosyl-(1→4)-β-D-glucopyranoside respectively. Structure, anomeric and absolute configuration of these substances were determined by 1H and 13C NMR spectroscopic methods, and mass spectrometric methods. The deacetylated epoxyalkyl β-D-glycosides were effective as irreversible active-site directed inhibitors of β-glycosidase from sweet almonds.
