Method for preparation of betulinic acid |
abstract |
The present invention relates to a method for preparation of betulinic acid from betulin. The method comprises oxidizing betulin to betulinic and/or betulonic aldehyde with a ruthenium based catalyst catalyzed oxidation process in the presence of an oxidant, and further converting the betulinic and/or betulonic aldehyde to betulinic acid. |
