(2R)-3-[(4-甲氧基苯基)甲氧基]丙烷-1,2-二醇

反应条件: temp:0.00; pressure:0.00; stir:; See reaction.notes.procedure_details.

实验步骤: The crude product of (S)-(+)-4-(4-methoxybenzyloxymethyl)-2,2-dimethyl-1,3-dioxolane (4.1 g) was dissolved in methanol (10 mL), added with 1 N hydrochloric acid and stirred at room temperature for one day. The reaction solution was adjusted to pH 6 by addition of saturated aqueous sodium hydrogencarbonate and extracted four times with dichloromethane. The organic layer was dried over anhydrous sodium sulfate, and the solvent was removed. The residue was purified by silica gel column chromatography to obtain (R)-(+)-3-(4-methoxybenzyloxy)-1,2-propanediol (2.4 g, yield: 69%). extracted four times with dichloromethane The organic layer was dried over anhydrous sodium sulfate the solvent was removed The residue was purified by silica gel column chromatography
