Development of designer natural product variants, 6-aza-artemisinins, enabled us to achieve structural modification of the hitherto unexplored cyclohexane moiety of artemisinin and concise de novo synthesis of the tetracyclic scaffold in just four steps from the modular assembly of three simple building blocks. This expeditious catalytic asymmetric synthetic approach generated lead candidates exhibiting superior in vivo antimalarial activities to artemisinin.
