title: 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.
