In CH2Cl2 in the presence of benzylamine, artemisinin transfers an oxygen atom from the intermediate open hydroperoxide to tertiary amines to form N-oxides and N-benzyl-11-azadesoxyartemisinin Base-catalyzed side reactions interfere with the corresponding reaction involving dihydroartemisinin. The reactions serve as a model for biological activity in which the act of binding to a protein liberates hydroperoxide. (C) 1999 Elsevier Science Ltd. All rights reserved.
