Abstract : The sequential Michael addition/retro-Claisen condensation of 1,3-diarylpropan-1,3-diones with nitrostyrenes is described. 4-Nitro-1,3-diarylbutan-1-ones were efficiently synthesized in good to high yield under mild, transition-metal-free condition. This one-step method involving sequential carbon-carbon bond formation and cleavage provides a good alternative to the synthesis of various γ-nitro ketones. Graphical abstract: The sequential Michael addition/retro-Claisen condensation of 1,3-diarylpropan-1,3-diones with nitrostyrenes is described. 4-Nitro-1,3-diarylbutan-1-ones were efficiently synthesized in good to high yield under mild and transition-metal-free condition.

The Michael addition of nitromethane to chalcones promoted by microwave irradiation without solvent afforded 1,3-diaryl-4-nitro-1-butanones in good yield. The products were characterised by IR, 1H NMR and elemental analysis.

In the presence of nickel(II) or cobalt(II)acetate-2,2'-bipyridine complexes, α,β-unsaturated ketones, methyl acrylate, and acrylonitrile were found to react with nitromethane, malononitrile, and aniline at room temperature under neutral condition to afford addition products in good yields.
