Mass and NMR spectra of haplophyllidine and perforine and of their derivatives
- 15 Downloads
The mass and NMR spectra of haplophyllidine, perforine, and their derivatives have been studied. The influence of the open and cyclic forms of the molecular ion on the nature of the fragmentation has been discussed. The main routes of fragmentation of the compounds considered are due to the presence of substituents at C8 and C4.
KeywordsMethoxyl Group Olefinic Proton Cyclic Form Isopropylidene Tetrahydroquinoline
