실험 절차

A mixture of 4-(2,3,4,6-tetra-O-acetyl-β-D-glucopyranosyloxy)-3-[(E)-2-(4-bromophenyl)vinyl]benzofuran (0.2 g), 3-butenoic acid (0.053 mL), triethylamine (0.22 mL), palladium (II) acetate (7 mg) and tris(2-methylphenyl)phosphine (19 mg) in acetonitrile (4 mL) was heated for reflux under an argon atmosphere for 8 hours. The reaction mixture was cooled to room temperature, and the insoluble material was removed by filtration. The filtrate was diluted with ethyl acetate. The solution was washed with 0.5 mol/L hydrochloric acid, water and brine successively, 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: n-hexane/ethyl acetate=1/1-dichloromethane/methanol=20/1) to give the title compound (0.17 g).
