Graphical Abstract
Malaria is a serious global health issue. Artemisinin combination treatments are the first-line drugs, but supplies are limited because artemisinin is obtained solely by extraction from Artemisia annua. A continuous-flow process that converts dihydroartemisinic acid into artemisinin (see scheme) was shown to be an inexpensive and scalable process that can ensure a steady, affordable supply of artemisinin.
