Reaction Conditions

Reaction Steps

Under an argon atmosphere, L-ascorbic acid (300 g) and sodium hydrogen carbonate (42.9 g) were added to water and the resultant mixture was stirred at room temperature for 30 minutes, then, glycidol (126 g) was added thereto. Thereafter, the mixture was heated up to 50° C. and stirred for 5 hours. Thereto, methanol was added and filtration was performed. The filtrate was concentrated under reduced pressure, and 457 g of the resultant residue was subjected to silica gel column chromatography. Elution was performed with chloroform/methanol/water(volume ratio:65/35/5), and concentration was performed under reduced pressure to obtain 3-O-glyceryl ascorbic acid (296 g).
