Non-electron-transfer quinone-mediated oxidative cleavage of cyclopropylamines. Implications regarding their utility as probes of enzyme mechanism

3,5-Di-tert-butyl-1,2-benzoquinone effects oxidative cleavage of cyclopropylamine (CPA) and its 1-phenyl analogue via o-quinoneimine intermediates, a reaction which may serve as a model for the inactivation of plasma amine oxidase by CPA
