CARBO- AND HETEROCYCLIZATION REACTIONS OF 2-(4-MORPHOLINYL)-1-PHENYLPROPENE AND NITROOLEFINS

Felluga, F.,Nitti, P.,Pitacco, G.,Valentin, E.

, p. 5667 - 5678 (2007/10/02)

The title enamine may exist in two double bond isomers.Both forms react with the nitroolefins under different conditions to afford, after hydrolysis, regioisomeric γ-nitroketones. γ-Dicarbonyl compounds are isolated from the hydrolysis at pH 2 of the 1,2-oxazine N-oxide systems, which in some cases have also been separated.
