| titleOfInvention | Method for preparing 3-o-alkyl-ascorbic acid |
| abstract | The present invention relates to a method for preparing 3- O- substituted ascorbic acid derivatives represented by formula 1, in which 5, 6-O-isopropylidene ascorbic acid is reacted with a halide in an organic solvent in the presence of the anion exchange resin absorbed with multi-iodine anions and then deprotected. The method of the present invention has an advantage of providing a target compound with high purity and high yield by finishing the reaction within a short period of time at room temperature. |
