2,3,4,6-TETRA-O-PIVALOYL-ALPHA-D-GLUCOPYRANOSYL BROMIDE - Reference Information
| introduction | 2,3,4,6-O-tetra-pentanyl-alpha-D-bromo-glucopyranose can be used to prepare canagliflozin. Canaglifloin Canagliflozin is the first SGLT2 inhibitor drug approved by FDA. It can reduce blood sugar by decomposing glucose and excreting it through the kidneys. It has broad prospects for the treatment of adult type 2 diabetes. |
| preparation method | using ALPHA-D-glucose as raw material, after reacting with tervaloyl chloride to protect all hydroxyl groups, then reacting with zinc bromide and trimethylbromosilane at -10 ℃ to form intermediate 4, and adding a small amount of thionyl chloride to the process of protecting group, so that the dosage of tervaloyl chloride is reduced by half, and the yield is not affected, the two-step yield is above 82%, and the total yield is more than 67%. |
