Electron impact mass spectra of six isomeric compounds, namely perezone, isoperezone, Ξ±-pipitzol, Ξ²-pipitzol, Ξ²-isopipitzol and dihydroisoperezinone have been recorded. The proposed fragmentation pathways leading to the formation of a number of important daughter ions have been confirmed from the co

β¦ Synopsis
In recent years the importance of mass spectrometry as a useful tool for structure elucidation studies has been well established, particularly in the field of natuml products. Although a large number of alkaloids have been examined in this connection (l), na report on the mass spectm of morphine group alkaloids had come to our attention until quite recently (2). The present paper describes mass spectra and geneml fmgmentation patterns of morphinan and some related compounds (3). The interpretation of the spectrum is based on an assumption that upon electron impact' one electron is mmoved either from the nitrogen atom or from the aromatic nucleus. The spectrum of the simplest pamnt compound, morphinan (I),.is shown in Fig. 1.
