Mass Spectrometry of 2a,4-Disubstituted 5-Benzoyl-2a,3,4,5-tetrahydro-2-phenoxy-azeto1,2-a1,5benzodiazepin-1(2H)-ones Under Electron Impact Ionization Conditions

摘要

The mass spectrometric fragmentation of 2a,4-disubstituted 5-benzoyl-2a,3,4,5-tetrahydro-2-phenoxy-azeto{[1,2-a]}[1,5]benzodiazepin-1(2H)-ones has been investigated by means of mass-analyzed ion kinetic energy spectrometry under electron impact ionization conditions. All compounds tend to lose different moieties, such as phenoxy, phenoxy and H, and phenoxyketene. Both [M +-PhO] and [M +-PhOH] ions could further lose CO, and the [M +-PhOCHCO] ions could lose propene or styrene, PhCON, PhCOHN, and other fragments.
