METHOD FOR PRODUCING 30-HALOGENATED BETULINIC ACID |
| 摘要 |
The invention discloses a method for producing 30-halogenated betulinic acid. Betulin is used as a raw material and selectively oxidized and halogenated to generate 30-betulinic acid, and the selected oxidation and halogenation agent has high selectivity and does not affect C-3 hydroxyl or carbon-carbon double bonds. Oxidation and halogenation are completed in one step, so the process route is short, the treatment method is simple, and the product is purified easily. |
