Mass spectral fragmentation amides

Two amidic pyrrolidine bases, odorine (2 R = H) and odorol (2 R = OH), have been isolated from the leaves of Aglaia odorata Lour. Their structures have been settled by n.m.r., i.r., and mass spectral analysis. The cinnamoyl residue in each was readily detected by the mass spectral fragmentation and, in the case of odorinol, by acid hydrolysis, which afforded cinnamic and 2-hydroxy-2-methyl-butanoic acids. ... [Pg.30]

Twelve volatile acyclic amines and amides (114-120,125-129) (Table VIII) from ponerine ants in the genus Mesoponera have been identified by gas chromatography-mass spectrometry and mass spectral comparison with authentic synthetic samples 41). The major aliphatic amine, A-isoamylnonylamine (114), shows a molecular ion at m/z 213, a-cleavage fragments at miz 156 (M — C4H9)... [Pg.288]
