## Mass spectrometry of the 4,4-dimethyloxazoline derivatives of isomeric octadecenoates (monoenes) Although 4,4-dimethyloxazoline (DMOX) derivatives of fatty acids have been widely used for structural analysis of fatty acids by mass spectrometry, spectra of relatively few authentic standards have

✦ Synopsis
The mass spectrometrical fragmentation patterns of the 4.4-dimethyloxazoline derivatives (DMOX) of the studied 0x0 fatty acids are easily to understand. The 0x0 group positions can be assigned unequivocally, The spectra are similar to those of the corresponding pyrrolidide derivatives. Since DMOX derivatization proofed to be good for the GC-MS analysis of epoxy fatty acids as the method could be interesting for studies on oxidized fatty acids, as well.
Massenspektrometrie der 4,4-Dimethyloxazoline von Oxooctnd e c ~~~s e n s p e k t r o m e t r i s c h e n
Fragmentierungsmuster der 4,4-Dimethyloxazolinderivate (DMOX) der untersuchten Oxooctadecansauren sind eindeutig interpretierbar, die L w der Ketogruppe ist jeweils richtig zuzuordnen. Die resultierenden Spektren sind denen der entsprechenden Pyrrolidid-Derivate sehr ahnlich. Da die DMOX-Derivatisierung auch fur die GC-MS-Analyse von Epoxifettsauren gut einsetzbar ist, konnte diese Methode von allgemeinerem Interesse fur Untersuchungen an oxidierten Fettsauren sein.
