| titleOfInvention | Dihydroarteannuic acid synthesis process |
| abstract | The invention relates to a dihydroarteannuic acid synthesis process, which comprises: dissolving arteannuic acid in an organic solvent, adding hydrazine hydrate and a catalytic amount of a transition metal compound, adjusting the reaction temperature to 25-100 DEG C, adding hydrogen peroxide to the reaction solution in a dropwise manner so as to make the arteannuic acid be reduced into the dihydroarteannuic acid by the diimine produced in the in situ manner, extracting and drying to obtain the dihydroarteannuic acid. The preparation method has characteristics of short synthesis reaction time and high dihydroarteannuic acid yield. |
