Mass spectral fragmentation of furanoeremophilane derivatives bearing oxygen-fuunction on B ring were investigated.It was found that mass spectra measured by direct inlet system gave characteristic retro-Diels-Alder fragmentations, while indirect introduction of the samples afforded intense peaks at m/e 159 and m/e 145 containing the furan moiety.Fragmentation patterns of other poly-functional derivatives were examined by measurements of accurate masses and metastable ions.
