  Reactions of CF3-enones with ethyl nitroacetate and nitromethane: synthesis of CF3-γ-nitroketones

  摘要：

  Reactions of alpha,beta-unsaturated CF3-ketones with nitromethane and ethyl nitroacetate have been investigated. We found that alpha,beta-unsaturated trifluoromethylketones react with ethyl nitroacetate in the presence of calcinated potassium fluoride to form two classes of 1,4-conjugated addition products: CF3-gamma-nitroketones and 6,6,6-trifluoro-2-nitro-5-oxohexanoates in nearly quantitative yields. The products obtained are precursors for CF3-pyrrolidine synthesis. (c) 2005 Elsevier Ltd. All rights reserved.
