• Stereospecific decomposition reactions of isomeric molecules of a series of 1-substituted quinolizidin-1-ols have been examined by using electron ionization mass spectra (E1-MS).Inspection of the MS indicates that the molecular ion and the other ions ([M-17]^+, m/z 154 and 168) for cis-isomers are much more abundant than those for trans-isomers. The configurations of epimers can be distinguished on the basis of the relative intensities of the molecular ion, the ions corresponding to [M-1]^+ and [M-17]^+ and [M-29]^+, and the ions at m/z 154 and 168 in EI-MS, and the peaks due to elimination of a hydroxyl radical from the molecular ion in the ion kinetic energy spectra.
