Reaction Steps
Under an argon atmosphere, 3-O-butylglyceryl ascorbic acid (4.98 g) obtained in Example 6 was stirred in DMSO(10 mL), and further, sodium hydrogen carbonate (0.33 g) was added. Thereafter, glycidol (1.46 g) was added and the mixture was heated up to 80° C. and stirred for 18 hours, followed by extraction with n-butnol. The extracted liquid was dried over anhydrous sodium sulfate, and concentrated under reduced pressure, and 6.23 g of the resultant residue was subjected to silica gel column chromatography. Elution was performed with chloroform/methanol/water(volume ratio:20/3/0.4), and concentration was performed under reduced pressure to obtain 3-O-butylglyceryl-2-O-glyceryl ascorbic acid (1.23 g).
