  Electron Impact Induced Loss of C-5/C-8 Substituents of 1,2,3,4-Tetrahydroisoquinolines, V: Synthesis and Mass Spectrometric Fragmentation of Dihydroisoindole Derivatives

  摘要：

  AbstractC‐8‐substituted N‐methyl‐1,2,3,4‐tetrahydroisoquinoline radical cations lose the complete substituent in a one step reaction giving rise to an unexpected ion at m/z 146, which is probably identical with the dihydroisoindolyl‐methyl‐cation A. The dihydroisoindoles 1, 10, and 16 were prepared as potentially alternative precursors of ion A. However, the ion at m/z 146 in their El mass spectra is of very low intensity, so CID‐experiments for structural comparison could not be performed. The electron impact induced fragmentations of 1, 10, and 16 are discussed.
