The new C-16-functionalized artemisinin derivatives were obtained through a novel one-pot synthesis of artemisitene (2) from naturally abundant artemisinin (1), followed by Michael addition with nucleophiles. The correlation points to the biological significance of the interaction of these derivatives with ferroprotoporphyrin IX and may provide a basis for primary screening of peroxidic antimalarials of similar structures.Mahidol UniversityChemistryArticleSCOPUS10.1021/jm960767v
