Resumen

The electron impact induced fragmentations of C- and N-methyl, benzyl, and prenyl substituted 2-oxopyrrolidinoindolines were studied using an ion trap mass spectrometer (IT-MS). Correlations of characteristic fragment ions of the 2-oxopyrrolidinoindoline skeleton with specific modifications of the substituents around it were supported by stepwise fragmentation MS/MS analysis and accurate mass measurements. The MS3 spectra evidenced the neutral loss of methyl- or benzylisocyanate from the 2-oxopyrrolidine ring, which would result in a rearranged stable quinolinium ion.
