Abstract

The mass spectral fragmentations of 2‐cyano‐2‐methylsparteine (1), 2‐cyano‐2‐phenylsparteine (2), 2‐cyano‐2‐(p‐tolyl)sparteine (3), 17‐cyanosparteine (4) and 17‐cyanolupanine (5) were investigated. Fragmentation pathways, whose identification was assisted by accurate mass measurements and a correlation between the abundances of the M^+•^ and the selected fragment ions of the investigated compounds, are discussed. The data obtained create the basis for distinguishing the structural metamers. Copyright © 2004 John Wiley & Sons, Ltd.
