85.4% | With silver carbonate; In toluene; at 20 - 75℃; for 21.0h;Inert atmosphere; | General procedure: To a stirred solution of methyl (2,3,4-tri-O-acetyl-alpha-d-glucopyranosyl)uronate bromide (3) in dry toluene under Argon atmosphere the corresponding dried alcohol was added and the solution was warmed to 75 C. Subsequently, silver carbonate was added in three portions over a period of 3 h. Then the reaction was stirred at room temperature for 18 h. Afterwards, the suspension was filtered and the filtrate was evaporated to dryness. Purification by flash chromatography (silica gel, cyclohexane-ethyl acetate 1:1) or recrystallisation from i-propanol gave the product 4. |
