    Abstract
    Reaction of ketoximes with methyl propiolate afforded geometrical isomers of the methyl 3-(hydroxyimino)propanoates 4 and of the O-vinyl oximes 5 as well as the 2-isoxazoline 6. With dimethyl penta-2,3-diendioate 8c reaction progressed via an O-alkylation to give the O-oxime ethers 9, only in the case of cyclopentanone oxime was the spirocyclic dihydroazepinol 11 also obtained, its identity has been confirmed by an X-ray structure determination.
