Procedure
-
To a solution of methyl α-L-fucopyranoside (250 mg, 1.4 mmol), N,N-diisopropylethylamine (217 mg, 1.68 mmol, 1.2 equiv) and 1 (48 mg, 0.14 mmol, 10 mol%) in acetonitrile (7 mL, 0.2 mol/L) was added benzoyl chloride (237 mg, 1.68 mmol, 1.2 equiv) at r.t. and the mixture was stirred for 20 hours. Methanol (1 mL) was added to the reaction mixture. The solvent was removed under reduced pressure and the residue was purified by column chromatography (ethyl acetate:hexane = 0:1 - 3:1 on silica gel) to give methyl 3-O-benzoyl-α-L-fucopyranoside as a white solid (362 mg, 91%).

Experimenter’s Comments
-
The reaction mixture was monitored by TLC (dichloromethane:methanol = 10:1, Rf = 0.50).
