A series of spiro[n.2]alkan-2-ones and their 6 and 7 oxa derivatives were subjected to acid catalysis. In the former series, products arising from hydroxyl(cyclopropyl)carbinyl cations are observed...

Lewis acid catalyzed rearrangement of α,β-epoxy oximes proceeds by oxirane cleavage α to the oxime moiety with an attendant pinacol type alkyl migration to the resonance stabilized carbenium ion at Cα, affording a 1,3-diketo-monoxime.
