In two steps from dihydroartemisinin, a small array of 16 semisynthetic C-10 pyrroleMannich artemisinin derivatives (7a−p) have been prepared in moderate to excellent yield. In vitro analysis against both chloroquine sensitive and resistant strains has demonstrated that these analogues have nanomolar antimalarial activity, with several compounds being more than 3 times more potent than the natural
