  • One-pot regioselective synthesis of substituted pyrazoles and isoxazoles in PEG-400/water medium by Cu-free nano-Pd catalyzed sequential acyl Sonogashira coupling–intramolecular cyclization

    Catalyst efficacy of in situ generated Pd-nanoparticles (PdNPs) in the regioselective one-pot synthesis of 3,5-di & 3,4,5-trisubstituted pyrazoles and 3,5-disubstituted isoxazoles in environmentally benign PEG-400/H2O medium, which involves the sequential (i) Cu-free acyl-Sonogashira coupling (ASC) and (ii) intramolecular ynone–amine cyclization under PTC conditions was described. The results of controlled
    在环境友好的PEG-400 / H 2中原位生成的Pd-纳米颗粒(PdNPs)在区域选择性一锅合成3,5-di和3,4,5-三取代的吡唑和3,5-二取代的异恶唑的催化剂效力描述了一种O介质,它涉及(i)在PTC条件下无Cu的酰基-Sonogashira偶联(ASC)和(ii)分子内的ynone-amine环化。受控实验的结果支持两个连续的催化循环(ASC /环化)的操作,并通过一锅法通过与炔酮结合的实现互补/相反的区域选择性。而且,就地一锅法反应序列的第一个催化循环后回收的PdNPs已连续五次再次使用。此外,在进行上述研究之前,某些常见的Pd-N-杂环卡宾(Pd-NHC)配合物在和有机物中催化相同的一锅两步反应顺序(无ASC /环化)的功效还优化了溶剂。还可以从中的Pd-NHC上方原位生成PdNP,但由于它们的尺寸较大,因此无法重复使用。
  • A highly efficient heterogeneous palladium-catalyzed cascade three-component reaction of acid chlorides, terminal alkynes and hydrazines leading to pyrazoles
    作者:Qiurong Chen、Fang Yao、Lin Yin、Mingzhong Cai
    DOI:10.1016/j.jorganchem.2015.12.037
    日期:2016.2
    MCM-41-immobilized palladium(II) complex [MCM-41-2N–Pd(OAc)2] and 1.0 mol% of CuI, acid chlorides were coupled with terminal alkynes in Et3N at 50 °C to give α,β-unsaturated ynones, which were converted in situ into pyrazoles by the cycloaddition of hydrazines at room temperature with acetonitrile as cosolvent. The cascade reactions generated a variety of pyrazole derivatives in moderate to good yields, and
    在0.5摩尔%的3-(2-基乙基基)丙基官能化的MCM-41固定的(II)配合物[MCM-41-2N-Pd(OAc)2 ]和1.0摩尔%的CuI的存在下,酰将其与末端炔烃在50°C的Et 3 N中偶合,得到α,β-不饱和炔酮,通过在室温下以乙腈为助溶剂将环加成,将其原位转化为吡唑。级联反应以中等至良好的产率生成了多种吡唑生物,并且这种非均相催化剂显示出比PdCl 2(PPh 3)2更高的催化活性,并且可以被回收并重复使用至少10次连续试验而活性没有降低。

  • Chemoselective synthesis of substituted pyrazoles through AgOTf-catalyzed cascade propargylic substitution–cyclization–aromatization
    作者:Su-Xia Xu、Lu Hao、Tao Wang、Zong-Cang Ding、Zhuang-Ping Zhan
    DOI:10.1039/c2ob27016a
    日期:——
    A cascade AgOTf-catalyzed chemoselective approach to 3,5/1,3-disubstitued pyrazoles from propargylic alcohols and para-tolylsulfonohydrazide has been developed. Good chemoselectivity is observed depending on the different substituents in the alkyne moiety of the propargylic alcohols, generating two different kinds of products through different aromatization mechanisms. The pyrazolo[5,1-a]isoquinoline skeleton can also be effectively constructed by this method through a cascade bicyclization process.
    开发了一种瀑布式AgOTf催化的化学选择性方法,能够从丙炔醇和对甲苯磺酰得到3,5/1,3二取代的吡唑。根据丙炔醇中炔烃部分的不同取代基,观察到良好的化学选择性,通过不同的芳构化机制生成两种不同类型的产物。该方法还可以通过级联双环化过程有效构建吡唑[5,1-a]异喹啉骨架。
