    摘要:
    在与活性亚甲基化合物的反应中,初级硝基化合物尚未用作氧化腈前体,因为通常用作脱水剂的试剂也与这些亲偶极体反应。然而,CuII 催化的环加成/缩合程序已被证明对这些底物是可行的,如果使用具有增强酸度(“活化”)的硝基化合物,则直接导致预期的多官能异恶唑。在不添加亲偶极体的情况下,这些硝基化合物会发生自缩合反应生成相应的呋喃。然而,与 3,4-二苯甲酰呋喃一样,苯甲酰硝基甲烷主要产生异构体 3-苯甲酰-4-硝基-5-苯基异恶唑,其结构已通过结晶分析证实。(© Wiley-VCH Verlag GmbH & Co. KGaA, 69451 Weinheim, Germany, 2009)

  • A Convenient Preparative Method of Nitrile Oxides by the Dehydration of Primary Nitro Compounds with Ethyl Chloroformate or Benzenesulfonyl Chloride in the Presence of Triethylamine
    作者:Tomio Shimizu、Yoshiyuki Hayashi、Hiroshi Shibafuchi、Kazuhiro Teramura
    DOI:10.1246/bcsj.59.2827
    日期:1986.9
    nitrile oxides (MeOCOC≡N→O, PhC≡N→O, and EtC≡N→O) were effectively generated in situ by dehydration of the corresponding primary nitro compounds (RCH2NO2) with PhSO2Cl or ClCOOEt in the presence of triethylamine. Various cycloadducts were prepared by the reaction of them with dipolarophiles. Some advantages of these methods are described in comparison with other known methods.
    三乙胺的存在下,通过用 PhSO2Cl 或 ClCOOEt 使相应的初级硝基化合物 (RCH2NO2) 脱,原位有效地生成了三种腈氧化物(MeOCOC≡N→O、PhC≡N→O 和 EtC≡N→O)。各种环加合物是通过它们与偶极试剂反应制备的。与其他已知方法相比,描述了这些方法的一些优点。
  • A New Synthetic Method of Alkyl Carbonocyanidate<i>N</i>-Oxides
    作者:Tomio Shimizu、Yoshiyuki Hayashi、Kazuhiro Teramura
    DOI:10.1246/bcsj.58.2519
    日期:1985.9
    A thermal decomposition of dimethyl nitromalonate to bis(carbomethoxy)furoxan was observed at about 170 °C. In the presence of dipolarophiles, an intermediate, methyl carbonocyanidate N-oxide MeOCOC≡N→O, could be trapped as cycloadducts in good yields by the 1,3-dipolar cycloaddition. Treatment of dimethyl nitromalonate in mesitylene at the refluxing temperature resulted in a formation of methyl 2-(hydroxyimino)-2-(2,4,6-trimethylphenyl)acetate.
    在约170°C下,观察到了二甲基硝基丙二酸酯的热分解反应,生成了双(羧甲酯)呋喃唑烷。在存在偶极亲电试剂的情况下,可以通过1,3-偶极环加成反应以良好产率捕获作为环加合物的中间体,即甲基碳二腈N-氧化物MeOCOC≡N→O。将二甲基硝基丙二酸酯在均三甲苯中回流处理,导致了甲基2-(羟基亚基)-2-(2,4,6-三甲基苯基)乙酸酯的形成。
  • New method of in situ generation of nitrile oxides by MnO2 oxidation of aldoximes

    DOI:10.1016/s0040-4039(99)01041-2
    日期:1999.7
    Manganese(IV) oxide (MnO2) was found to oxidize aldoximes to nitrile oxides. Nitrile oxides were trapped in situ with dipolarophiles to furnish 2-oxazolines. The best results were obtained with hydroximinoacetates as nitrile oxide precursors.

  • Stability of electron deficient activated nitronates under neutral and Lewis acid catalyzed conditions. Facile nitronate cycloaddition reactions to the magnesium alkoxides of allylic alcohols leading to isoxazolidines and isoxazolines
    作者:Shuji Kanemasa、Shinsuke Kaga、Eiji Wada

    日期:1998.11
    exceptionally high reactivity to the magnesium alkoxides of allylic alcohols. Isoxazolidines or isoxazolines are formed as cycloadducts, depending upon the substitution pattern of the allylic alcohols. When the latter C-monosubstituted nitronate is treated with a catalytic amount of boron trifluoride etherate, the corresponding nitrile oxide is smoothly generated through β-elimination of methanol.

  • New methods of preparation of nitrile oxides and the corresponding disubstituted furoxans by interaction of N2O4 with salts of substituted dinitromethanes
    作者:N. N. Makhova、I. V. Ovchinnikov、V. G. Dubonos、Yu. A. Strelenko、L. I. Khmel'nitsky
    DOI:10.1007/bf00699994
    日期:1993.1
    A new method of generation of nitrile oxides through interaction of N2O4 with salts of substituted dinitromethanes (1) has been worked out. It has been shown by1H,13C,14N NMR spectroscopy that this reaction proceeds via dinitronitrosomethyl intermediates (one of these has been isolated), and that the reaction is feasible only for substituents capable of conjugation with the nitrile oxide fragment.
    已经研究出一种通过 N2O4 与取代二硝基甲烷 (1) 的盐相互作用生成腈氧化物的新方法。1H、13C、14N NMR光谱表明,该反应通过二亚硝基甲基中间体(其中之一已被分离)进行,并且该反应仅对于能够与氧化腈片段缀合的取代基是可行的。在所得腈氧化物环二聚化的基础上,开发了合成对称取代呋喃的制备方法。
