Ozonolysis of α-ethylidene azetidinones (1) and (10) did not provide the expected α-oxoazetidinones, but afforded α-amino acid-N-carboxyanhydrides (3) and (11).

Ozonolysis of (E)-7-ethylideneoctane-2-spirocyclohexan>-8-one failed to provide the α-oxoazetidinone 2, but afforded an α-amino acid-N-carboxyanhydride nonane-2-spirocyclohexane>-7,9-dione 5. octane-2-spirocyclohexane>-7,8-dione 2 was instead obtained from the trans-ketone 9 by a sequence involving Baeyer-Villiger oxidation of the azido ketone 10.
