The electron impact mass spectra of nine solanidane N-oxides show, in addition to the known typical fragmentation pattern of the solanidane moiety, the fragment ions [M - C5H9]+ and [C6H12NO]+, due to thermal Cope syn-eliminations caused by the N-oxide function and subsequent cleavage of the bonds between C(22) and C(23) and between C(20) and C(22), respectively, in the so-obtained cyclic N,N-dialkylhydroxylamines.
