Oxygen Isotopes

Fourier transform infrared (FTIR) and resonance Raman (RR) spectroscopies have been employed to investigate the reductive cleavage of the O-O bond of the endoperoxide moiety of the antimalarial drug artemisinin and its analog trioxane alcohol by hemin dimer. We have recorded FTIR spectra in the nu(O-O) and nu(as)(Fe-O-Fe) regions of artemisinin and of the hemin dimer that show the cleavage of the endoperoxide and that of the hemin dimer, respectively. We observed similar results in the trioxane alcohol/hemin dimer reaction.
