实验过程
Attempts to prepare an hydrazide derivative of artesunate were unsuccessful and resulted in the formation of dihydroartemisinin due to the cyclization reaction. Artelinate was synthesized from dihydroartemisinin as previously described (Shrimali et al. (1998) Indian J. Chem. 37B:1161-1163). Artelinic acid (0.1 g, 0.24 mmol) was dissolved in anhydrous acetonitrile (0.48 mL). To this solution, 1-hydroxybenztriazole (HOBt) (0.038 g, 0.29 mmol) was added, followed by addition of ethyl dimethylethylcarbodiimide (0.055 g, 0.29 mmol). The reaction mixture was stirred at room temperature and monitored by thin-layer chromatography (TLC) until all the acid was converted to the HOBt ester.
