Electron impact mass spectra of meliacins |

| Authors: | K P Madhusudanan B Saikia B N Goswami R K Mathur |
| Abstract: | The electron impact mass spectra of some new meliacins and their derivatives are discussed. The major fragmentation modes include the functional group losses, the different ring cleavages and the loss of the furan residue as neutral fragments. A mechanism for the loss of the furan moiety from the molecular ion is discussed in detail with the help of deuterium labelling, high resolution and metastable data. |
