Oxidation of diterpene alkaloids by dimethyldioxirane was studied with eldeline, talatizamine, aconitine, and zongorine as examples. Nitrones and 19-oxo derivatives of bases were obtained. The results of the oxidation allow one to draw an analogy with the oxidation by KMnO4 and to suggest a mechanism of the reaction.
