| titleOfInvention | Method for preparing artemisinin for malaria |
| abstract | The invention discloses a method for preparing artemisinin for malaria. Firstly, dihydro-artemisinic acid is obtained by artemisinic acid under the effect of a reducing agent such as sodium borohydride /nickel chloride or hydrogen/a metal catalyst, then, under the existence of the catalyst, the dihydro-artemisinic is oxidized to be peroxide artemisinic acid through peroxide, and finally, an objective product-the artemisinin can be obtained with high efficiency under the catalyzing of the acid and the effect of oxygen. Compared with the prior art, the method for preparing the artemisinin for malaria has the advantages that the reagent is cheap and easy to obtain, short in synthetic route, high in reaction selectivity, environment-friendly in the process of preparation, easy to operate, simple in post-processing, high in total collection efficiency and suitable for industrialized production. |
