C-16 Artemisinin Derivatives and Their Antimalarial and Cytotoxic Activities: Syntheses of Artemisinin Monomers, Dimers, Trimers, and Tetramers by Nucleophilic Additions to Artemisitene

Abstract

Nucleophilic additions of lithium keto and ester enolates and mono- and bifunctional Grignard reagents to artemisitene provided C-16-derived artemisinin monomers, dimers, trimers, and tetramers whose antimalarial and cytotoxic activities have been evaluated.
