Semisynthetic Artemisinin, the Chemical Path to Industrial Production
A new commercial-scale alternative manufacturing process to produce a complementary source of artemisinin to supplement the plant-derived supply is described by conversion of biosynthetic artemisinicacid into semisynthetic artemisinin using diastereoselective hydrogenation and photooxidation as pivotal steps. This process was accepted by Prequalification of Medicines Programme (PQP) in 2013 as a first
