  • Domino Transformations of<i>gem-</i>Trifluoroacetyl(bromo)alkenes under the Action of Secondary Amines
    作者:Alexander Yu. Rulev、Igor A. Uchakov、Valentin G. Nenajdenko、Elisabeth S. Balenkova、Mikhail G. Voronkov
    DOI:10.1002/ejoc.200700606
    日期:2007.12
    underwent aza-Michael/hydroxyalkylation domino reactions triggered by secondary amines to give unexpectedly 2-amino-1-trifluoromethyl indenols in good yields. The process was found to involve the intermediate formation of captodative aminoalkenes. Treatment of 2-bromo-3-thienyl derivatives with the same nucleophiles afforded the captodative trifluoroacetyl(amino)alkenes. The indenols obtained in this reaction
    2-溴-3-芳基丙烯基三氟甲基酮经历由仲胺引发的氮杂-迈克尔/羟烷基化多米诺反应,意外地以良好的产率得到2-氨基-1-三氟甲基茚醇。发现该过程涉及俘获氨基烯烃的中间形成。用相同的亲核试剂处理 2-bromo-3-thienyl 衍生物得到三氟乙酰基(氨基)烯烃。在该反应中获得的茚醇可以通过酸水解转化为相应的茚满酮。(© Wiley-VCH Verlag GmbH & Co. KGaA, 69451 Weinheim, Germany, 2007)
  • Baylis–Hilman reaction for α,β-unsaturated trifluoromethyl ketones
    作者:Valentine G. Nenajdenko、Sergey V. Druzhinin、Elizabeth S. Balenkova
    DOI:10.1070/mc2006v016n05abeh002368
    日期:2006.1
    The reaction of beta-substituted alpha,beta-unsaturated CF3 ketones with acrylonitrile under the conditions of the Baylis-Hilman reaction was found to proceed as 1,2-addition.
  • Stereoelectronic structure of α-bromoalkenyl trifluoromethyl ketones
    作者:N. N. Chipanina、T. N. Aksamentova、A. Yu. Rulev
    DOI:10.1134/s1070428009100017
    日期:2009.10
    The results of quantum-chemical calculations at the B3LYP/6-311G** level of theory showed that (Z)-alpha-bromo-beta-arylalkenyl trifluoromethyl ketones are more stable than the corresponding E isomers by 4-5 kcal/mol. Relatively large positive charge on the olefinic beta-carbon atom and strong polarization of the C=C bond in both Z-s-cis and Z-s-trans conformers makes bromoalkenyl trifluoromethyl ketones the most potent Michael acceptors among alpha,beta-unsaturated carbonyl compounds. The calculated data are very consistent with the experimental IR spectra.
  • Reactions of CF3-enones with ethyl nitroacetate and nitromethane: synthesis of CF3-γ-nitroketones
    作者:Valentine G. Nenajdenko、Sergey V. Druzhinin、Elizabeth S. Balenkova
    DOI:10.1016/j.tetlet.2005.10.095
    日期:2005.12
    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.
  • Synthesis of trifluoromethyl derivatives of pyrrole. Reaction of  , -unsaturated trifluoromethyl ketones with sodium cyanide
    作者:V. G. Nenajdenko、S. V. Druzhinin、E. S. Balenkova
    DOI:10.1023/b:rucb.0000012372.68456.6f
    日期:2003.11
    An efficient preparative procedure was developed for the synthesis of 5-hydroxy-5-trifluoromethyl-2-pyrrolidones by the reaction of α,β-unsaturated trifluoromethyl ketones with sodium cyanide. Dehydration of these reaction products under mild conditions afforded previously unknown 5-trifluoromethyl-3-pyrrolin-2-ones.
