Abstract Enehydroxylamines, derived from carbocyclic and heterocyclic 1, 3-dioxo compounds, react with a variety of unsaturated electrophiles to give, in good to excellent yields, substances that in general undergo 3, 3-sigmatropic rearrangements either spontaneously or upon heating. In those cases in which such reactions failed, addition of sodium hydride was found to induce the transformation. A study of the rearrangement by ...
