Mass spectrometry of some derivatives of 5-(indol-2-yl)pyrimidine

Celewicz L., Frański R., Urjasz H., Płaziak A.S.

Polish Journal of Chemistry

1998

Vol. 72, nr 4

725-734

The electron impact (EI) and liquid secondary ion (LSI) mass spectra of 5-(indol-2--yl)pyrimidine derivatives are discussed. It was established that 5-(indol-2--yl)uracils, instead of the cleavage of the single carbon-carbon bond between uracil and indole ring, form stable ions with additional linkage between 4O-oxygen of uracil and CH2 group at the 3 position of indole moiety. Similarly, 5-(indol-2-yl)cytosines yield stable tetracyclic ions with new linkage between 4N-nitrogen of cytosine and CH2 group at the 3 position of indole ring.
