Abstract

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 – C~5~H~9~]^+^ and [C~6~H~12~NO]^+^, 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.
