Reactions of tropolone (1a) and 3-isopropenyl-, 3-acetyl-, 3-acetamido-, and 5-bromotropolones 1b-e with 2,3,4,6-tetra-O-acetyl-α-D-glucopyranosyl bromide were carried out in the presence of silver carbonate at 80℃. Unsubstituted, 3'-/7'-isopropenyl-, 7'-acetyl-, 7'-acetamido-, and 5'-bromo-substituted 2'-troponyl 2,3,4,6-tetra-O-acetyl-β-D-glucopyranosides were respectively obtained.
