실험 절차

To a solution of 5-methoxy-2-(4-[2-(methoxymethyloxy)ethyl]benzyl)phenol (0.19 g) and 2,3,4,6-tetra-O-acetyl-1-O-trichloroacetoimidoyl-α-D-glucopyranose (0.40 g) in dichloromethane (15 mL) was added boron trifluoride diethyl ether complex (0.088 mL), and the mixture was stirred for 20 minutes. To the reaction mixture was added a saturated aqueous sodium hydrogen carbonate, and the organic layer was separated and dried over anhydrous sodium sulfate. The solvent was removed under reduced pressure, and the residue was purified by column chromatography on silica gel (eluent: hexane/ethyl acetate=1/1) to give 5-methoxy-2-{4-[2-(methoxymethyloxy)ethyl]-benzyl}phenyl 2,3,4,6-tetra-O-acetyl-β-D-glucopyranoside (0.33 g).
