Abstract
The ultraviolet spectra, basic strengths, and N-alkyl groups of the aconite alkaloids are discussed. Pyropseudaconine has been shown to contain a conjugated system. The formulation C19H19–2,(OH)3,(OCH3)4NC2H5has been confirmed for lycoctonine. Study of its oxidation products has shown that lycoctonine has a methylene group adjacent to the nitrogen and a primary hydroxyl group. The two remaining hydroxyls have been shown to be vicinal, with one probably secondary and the other tertiary. A carbinolamine structure is suggested for hydroxylycoctonine. The new bases, isolycoctonine, desoxylycoctonine, and des-(oxymethylene)-lycoctonine are described.
