    Nouvelle voie d'acces aux β-nitroenones premiere preparation de β-nitroenones acycliques
    摘要:
    We describe here a new and mild method of synthesis of acyclic beta-nitroenones. Nitroepoxydes IVunderbar, prepared by epoxydation of the allylic nitroolefins IIIunderbar, react with silicagel or aluminium isopropoxide according to the substrate, to give the nitroethylenic alcohols Vunderbar. Their oxydation by PCC under sonication leads to the beta-nitroenones VIunderbar.

  • Reaction of β-Nitroenones with Active Methylene Compounds Anions

    Abstract β-Dicarbonyl compounds, phenylsulfonylacetate, cyanoacetate and malonitrile sodium enolates add to β-nitroenones at the α-carbon atom of the unsaturated carbonyl system and provide access to highly functionalised intermediates.

    A new synthesis of 2-isoxazoline 2-oxides starting from unsaturated nitro compounds is described. A facile and convenient preparation of β-alkyl substituted β-nitroenones and their conversion to β-nitrosulfides are recorded. Treatment of these compounds with potassium tert-butoxide at −78°C followed by immediate quenching with acetic acid provides access to 5-hydroxy-4-(phenylthio)-2-isoxazoline 2-oxides

  • Addition of Ketone and Ester Lithium Enolates to (E)-.beta.-Nitroenones
    作者:Raphaeel Schneider、Philippe Gerardin、Bernard Loubinoux
    DOI:10.1021/jo00125a027
    日期:1995.10
    Under kinetic control at -78 degrees C, reactions of ketone or ester lithium enolates with (E)-beta-nitroenones 2 occurred at the carbonyl group giving (E)-3-hydroxy-5-nitroalk-4-enones 6 or (E)-3-hydroxy-5-nitroalk-4-enoates 13, respectively, with good regioselectivity. When the temperature of the reaction between 2 and lithium ketone enolates was allowed to warm up to -10 degrees C before hydrolysis, solely the 2-(nitromethyl) 1,4-diketones 8 were obtained. Steric factors which might influence the observed stereoselectivities during the nucleophilic attack on beta-nitroenones are discussed.
