Reaction Conditions:

with 5%-palladium/activated carbon;hydrogen in methanol at 20;Darkness;Green chemistry;

Steps:

15 Example 15 Preparation of 2-(4-hydroxyphenyl)ethyl-β-D-glucopyranoside (resorpirin)

1.1 g (2.8 mmol) of 1-O-(4-benzyloxy)-phenylethyl yl -β-D- glucopyranoside and 5% Pd / C 0.1 g of catalyst, and then repeatedly evacuated air charge of hydrogengas 3-5 times, and 20 mL of anhydrous methanol, protected from light, stirred at room temperature under a hydrogen atmosphere overnight.Filtration, concentration to dryness under reduced pressure,and recrystallized from ethanol to give 1-(4-hydroxy)-phenethyl-β-D-s-glucopyranoside as a white powder, which is aweight of 0.78 g. The yield was 93%.
