  • Synthesis of 4-Fluoromethylsydnones and their Participation in Alkyne Cycloaddition Reactions
    作者:Robert S. Foster、Harry Adams、Harald Jakobi、Joseph P. A. Harrity
    DOI:10.1021/jo400381a
    日期:2013.4.19
    We report the synthesis and some structural studies of 4-trifluoromethyl, 4-difluoromethyl-, and 4-monofluoromethylsydnones. All but the latter compounds are stable and represent effective precursors to a range of pyrazoles after cycloaddition reactions with alkynes. The cycloadditions are generally highly regioselective and provide 5-fluoromethylpyrazole products, although we have observed that Bn-substituted
    我们报告了4-三甲基,4-二甲基-和4-单甲基sydnones的合成和一些结构研究。除后者以外的所有化合物都是稳定的,并且在与炔烃进行环加成反应后,代表了一系列吡唑的有效前体。尽管我们已经观察到Bn取代的sydnones可以提供意想不到的炔烃插入模式以生成3-甲基异构体,但是环加成物通常具有高度的区域选择性并提供5-甲基吡唑产物。
  • Unexpected ring opening of pyrazolines with activated alkynes: synthesis of 1<i>H</i>-pyrazole-4,5-dicarboxylates and chromenopyrazolecarboxylates
    作者:Sai Teja Kolla、Nageswara Rao Rayala、Balasubramanian Sridhar、China Raju Bhimapaka
    DOI:10.1039/d1ob01727f
    日期:——
    prepared by reacting pyrazolines with activated alkynes under neat conditions without a catalyst. The products were formed via unexpected ring opening of pyrazolines with the elimination of styrene/ethylene. These types of transformations are unknown and the products formed were confirmed using their spectral/analytical data. In addition, the structures of compounds 5e and 5n were confirmed by single-crystal
    1 H -Pyrazole-4,5-dicarboxylates 和 chromenopyrazole carboxylates 是通过在没有催化剂的纯净条件下使吡唑啉与活化的炔烃反应制备的。产物是通过吡唑啉的意外开环和苯乙烯/乙烯的消除而形成的。这些类型的转化是未知的,并且使用它们的光谱/分析数据确认了所形成的产物。此外,化合物5e和5n的结构通过单晶X射线分析证实。进行了对照实验以支持所提出的反应机理。
  • Site selectivity in the reactions of 1,3-dipoles with norbornadiene derivatives
    作者:D. Cristina、M. De Amici、C. De Micheli、R. Gandolfi
    DOI:10.1016/s0040-4020(01)92451-2
    日期:1981.1
    2-diazopropane and C-pnenyl-N-methyl-nitrone react with the sole tetrasubstituted double bond of 1a–c in stereo- and site-specific cycloadditions. The quantitative evaluation of the two possible reaction paths was performed by glc analysis. The compounds detected were those arising from Diels-Alder cycloreversions of the thermally labile intermediate adducts 2 and 3 (Scheme 1). The results were rationalized
    芳基叠氮化物苄腈氧化物和二苯基腈亚胺与降冰片二烯衍生物1a–c的环加成反应显示出不同程度的位点和立体选择性。对于双极性亲和剂1a,芳基叠氮化物苯甲腈氧化物优先攻击电子贫的四取代双键,而在1b和1c的情况下,则是进入环加成的取代双键。相比之下,2-重氮丙烷和C-亚苯基-N-甲基-硝基与立体和位点特定的环加成反应中与1a–c的唯一四取代双键反应。通过glc对两种可能的反应路径进行定量评估分析。检测到的化合物是由热不稳定的中间体加合物2和3的Diels-Alder环还原所产生的化合物(方案1)。在仅考虑边界轨道相互作用的定性摄动处理的基础上,对结果进行了合理化。
  • Synthesis of fully substituted pyrazoles from pyridinium 1,4-zwitterionic thiolates and hydrazonoyl chlorides <i>via</i> a [[3 + 3] − 1] pathway
    作者:Bin Cheng、Bian Bao、Wei Xu、Yuntong Li、Hui Li、Xinping Zhang、Yun Li、Taimin Wang、Hongbin Zhai
    DOI:10.1039/d0ob00224k
    日期:——
    practical protocol for the synthesis of fully substituted pyrazoles from pyridinium 1,4-zwitterionic thiolates and hydrazonoyl chlorides in excellent yields under mild conditions is described. The transformation proceeds via an unusual [[3 + 3] - 1] pathway, which involves a formal [3 + 3] cascade cyclization followed by a spontaneous ring-contraction/sulfur extrusion reaction from 4H-1,3,4-thiadiazine intermediates
    描述了一种新颖实用的方案,可在温和的条件下以极佳的收率由吡啶鎓1,4-两性离子硫醇盐和酰合成全取代的吡唑。转化是通过不寻常的[[3 + 3]-1]途径进行的,该途径涉及正式的[3 + 3]级联环化,然后由4H-1,3,4-噻二嗪中间体进行自发的环收缩/硫磺挤出反应。
  • One-Pot Synthesis of Functionalized 3-Aryl-1-phenyl-1<i>H</i>-pyrazoles from Hydrazonoyl Chlorides and Acetylenic Esters in the Presence of Ph<sub>3</sub>P
    作者:Issa Yavari、Gholamhossein Khalili、Anvar Mirzaei
    DOI:10.1002/hlca.200900246
    日期:2010.2
    The zwitterionic 1 : 1 intermediates generated by addition of Ph3P to acetylenic esters is trapped by 1‐[(aryl)chloromethylene]‐2‐phenylhydrazines (=N‐phenylarenecarbohydrazonoyl chlorides) to yield functionalized 3‐aryl‐1‐phenyl‐1H‐pyrazoles in good yields.
    将Ph 3 P加到炔属酯中生成的两性离子1:1中间体被1-[((芳基)亚甲基] -2-苯基(= N-苯基芳基碳酰)捕获)生成官能化的3-芳基-1-苯基-1 H-吡唑类化合物的收率很高。
