Monoelectronic reduction of dihydroartemsisinin (DHA): pH dependence and product analysis

The reaction of dihydroartemisinin (DHA) with solvated electrons (e(solv)(-)) generated under radiolytic conditions showed high pH dependence. The reduction performed under neutral conditions led to the formation of compound P1 deriving from the initial alkoxyl radical as the only detectable product. (C) 2013 Elsevier Ltd.
