Guo-Feng Wei, Jin-Sheng Cheng, Zu-Liang Huang, You-Cheng He

An efficient reductive preparation of dihydroartemisinine from artemisinine with KBH4 in the presence of phase transfer catalyst was reported in this paper. The influences of the amount of reductant, catalysts, reaction temperature as well as reaction time were investigated in this paper.
