Reduction of qinghaosu (artemisine) (I) by means of sodium borohydride gives a hemiacetal, artemisininelactol (II). Interaction of the latter compound with methanol in the presence of boron triftuoride gives artemether. It can be prepared even more easily by treating artemisininelactol with methanol in acidic medium. The epimers can be separated by chromatography. However, the product without separation of epimers has been used for clinical studies.
