Procedure
-
To a solution of salicin (200 mg, 0.7 mmol) in DMF (2 mL) was added benzaldehyde dimethyl acetal (125 µL, 0.8 mmol) and p-TsOH・H2O (12 mg, 0.07 mmol) and the mixture was stirred at 80 °C for 2 hours. The reaction was quenched with triethylamine (19 µL, 0.14 mmol) and the solvent was removed under reduced pressure. The residue was purified by column chromatography (ethyl acetate:hexane = 10:90 - 85:15) to give 1 as a white solid (165 mg, 63%).
