Alkaloids from croton species. Part VI. Mass spectrometric studies of the crotonosine alkaloids
Abstract
The mass spectra of crotonosine and some related compounds are reported and the composition of the major fragments determined by high-resolution mass measurements. Modes of fragmentation are discussed. In addition the mass spectra of the model compound tetrahydroisoquinoline and its N-methyl and N-acetyl derivatives are reported and discussed.
