A process for preparation of ether derivatives of dihdroartemisinin |
| abstract |
The present invention relates to a facile and cost-effective process for the preparation of ether derivatives of dihydroartemisinin. The present invention further enables preparation of pure β-ether derivatives of dihydroartemisinin, commonly known as Artemether, the methyl ether derivative and Arteether, the ethyl ether derivative, which are well-known antimalarial agents without using an organic pro-acid. This invention also discloses a novel epimerisation process for the a-ether derivatives of dihydroartemisinin in β- isomer. |
