Abstract

A series of aminotroponimine and aminotropone derivatives were studied by electrospray mass spectrometry. MS and MS/MS data were acquired according to automated procedures. In the case of mono- and di-halogenated compounds, their specific behavior upon collisionally-activated dissociation conditions provided rapid structural assignments through inexpensive isotopic labeling MS/MS experiments.
