We describe here a new and mild method of synthesis of acyclic β-nitroenones. Nitroepoxydes IV, prepared by epoxydation of the allylic nitroolefins III, react with silicagel or aluminium isopropoxide according to the substrate, to give the nitroethylenic alcohols V. Their oxydation by PCC under sonication leads to the β-nitroenones VI.
