Method for producing L-ascorbic acid 2-phosphates |
| abstract |
A method for producing L-ascorbic acid 2-phosphates, is disclosed which comprises phosphorylating L-ascorbic acid whose hydroxyl groups at the 5- and 6-positions are unprotected or protected with a protective group, or salts thereof, with a phosphorus oxyhalide to form corresponding L-ascorbic acid 2-phosphates, wherein a reaction mixture obtained after the phosphorylation reaction is heated to convert by-products derived from L-ascorbic acid into L-ascorbic acid, which again is subjected to the phosphorylation reaction with the phosphorus oxyhalide. The method produce L-ascorbic acid 2-phosphates in a high yield and at a high purity with simple operations. |
