実験手順
Under an argon atmosphere, water and sodium hydrogen carbonate (1.42 g) were added to 3-O-glyceryl ascorbic acid (1.42 g) obtained in Example 1, and the mixture was stirred at room temperature for 30 minutes. To the mixture, benzyl bromide (2.61 g) was added, and the resultant mixture was heated up to 50° C. and stirred for 2 hours. Thereafter, the mixture was concentrated under reduced pressure, then, dissolved in methanol. Then, the resultant solution was dried over anhydrous sodium sulfate, and concentrated under reduced pressure, and 6.13 g of the resultant residue was subjected to silica gel column chromatography. Elution was performed with chloroform/methanol/water(volume ratio:10/3/0.4), and concentration was performed under reduced pressure to obtain to obtain 3-O-glyceryl-2-O-benzyl ascorbic acid (2.47 g).
