The reaction of .ALPHA.-substituted ketones with N-alkylhydroxylamines.

抄録

N-Methyl- and N-benzylhydroxylamine reacted smoothly with ethyl acetoacetate to afford the pyrroline compounds 1 and 2, respectively. On the other hand, the reaction of N-cyclohexylhydroxylamine gave the nitrone compound 3. Other active methylene compounds, i.e., diethyl acetonedicarboxylate, benzoylacetone and nitroacetone, reacted with methylhydroxylamine to give the N-methylpyrrole 6, the nitrone 7 and the isoxazoline 8, respectively.
