摘要	Friedel-crafts alkylation of 1,3-dimethoxybenzene with O-acetyldihydroqinghaosu gave a pair of 11-epimers of 12-(2,4-dimethoxyphenyl)deoxoqinghaosu 2 and 2'. The antimalarial activity of 11 β-epimer 2 was comparable with that of artemether. Compound 2 reacted smoothly with ferrous ions or L-cysteine and catalytic amounts of ferrous ions to give a series of products derived from the previously postulated C-centered free radical, in particular the primary C-centered free radical. However, 11α-epimer 2'was almost inert to ferrous ions and also showed low antimalarial activity. The identification of free radical mediated products and the correlation between chemical reactivity and bio-activity once again provided evidence for the key role of primary carbon-centered free radicals in the antimalarial activity of the qinghaosu seres of compounds.
