Artesunic acid 5, the hemisuccinate derivative of dihydroartemisinin 2, is the only clinically useful water-soluble derivative of artemisinin 1. However, being a lactol ester, it is rapidly hydrolyzed back to dihydroartemisinin in aqueous alkaline solution, a reaction that seriously limits its utility. A new series of potentially more stable linker-based hemisuccinate derivatives 12a–i and 14a–c have been prepared
