  • A General and Regioselective Synthesis of 5-Trifluoromethyl-pyrazoles
    作者:Robert S. Foster、Harald Jakobi、Joseph P. A. Harrity
    DOI:10.1021/ol3021918
    日期:2012.9.21
    Two synthetic approaches to 4-trifluoromethylsydnones, a novel class of these mesoionic reagents, are reported. These compounds undergo regioselective alkyne cycloaddition reactions, thereby providing a general approach to 5-trifluoromethylpyrazoles. This method has been employed in a short formal synthesis of the herbicide fluazolate.
    报道了两种合成方法4-三甲基sydnones,这些新的一类这类中性离子试剂。这些化合物进行区域选择性炔烃环加成反应,从而为5-三甲基吡唑提供了一种通用方法。该方法已用于除草剂唑酸盐的短形式合成中。
  • 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。
  • Efficient Copper-Catalyzed Synthesis of Substituted Pyrazoles at Room Temperature
    作者:Haifeng Wang、Xiangli Sun、Shuangling Zhang、Guanglu Liu、Chunjie Wang、Lili Zhu、Hui Zhang
    DOI:10.1055/s-0037-1610330
    日期:2018.12
    method for the synthesis of pyrazoles through a copper-catalyzed condensation reaction has been developed. The new catalytic system not only maintained a broad substrate scope but was also active under acid-free reaction conditions, overcoming the conventional requirement for an acid-catalyzed system. Furthermore, the copper catalyst enabled this reaction to be performed at room temperature and in a short
    已开发出一种通过催化缩合反应合成吡唑的有效方法。新的催化体系不仅保持了广泛的底物范围,而且在无酸反应条件下也具有活性,克服了对酸催化体系的传统要求。此外,催化剂使该反应能够在室温下和较短的反应时间内进行。
  • Application of Fe3O4@SiO2@sulfamic acid magnetic nanoparticles as recyclable heterogeneous catalyst for the synthesis of imine and pyrazole derivatives in aqueous medium
    作者:B. Zakerinasab、M. A. Nasseri、H. Hassani、M. M. Samieadel
    DOI:10.1007/s11164-015-2204-1
    日期:2016.4
    Sulfamic acid supported on Fe3O4@SiO2 superpara magnetic nanoparticles was successfully applied as a recyclable solid acid catalyst with a large density of sulfamic acid groups for the synthesis of pyrazole derivatives, an important class of potentially bioactive compounds. The products are obtained in high yield from the one-pot reaction procedure involving dicarbonyl compounds and hydrazines/hydrazides. This new method totally avoids the use of toxic or expensive solvents and organic acids in this reaction.
    负载于Fe3O4@SiO2超顺磁性纳米颗粒上的氨基磺酸作为具有大量氨基磺酸基团的固态可回收酸性催化剂,成功应用于吡唑类衍生物的合成,这是一类潜在的生物活性化合物。通过活性双羰基化合物与/酰的一锅法反应,获得了高产率的目标产物。这种新方法完全避免了在该反应中使用有毒或昂贵的溶剂和有机酸。
  • PEG–SO3H as a mild, efficient and green catalytic system for the synthesis of pyrazole derivatives in aqueous medium
    作者:M. A. Nasseri、S. A. Alavi、B. Zakeri Nasab
    DOI:10.1007/s13738-012-0143-y
    日期:2013.4
    A versatile, alternative and environmentally benign strategy for the synthesis of a series of pyrazoles has been successfully performed in water using PEG–SO3H as an acidic catalyst. The products are obtained in high yield from the one-pot reaction procedure involving dicarbonyl compounds and hydrazines/hydrazides. This new method totally avoids the use of organic acids and toxic or expensive solvents in this reaction. The catalyst is waste-free, easily prepared, and efficiently re-used.
    相中使用PEG-SO3H作为酸性催化剂,成功地实现了一种合成一系列吡唑类化合物的多功能、替代性及环境友好型策略。通过涉及二羰基化合物与酰/酰化合物的单锅反应程序,产物以高收率获得。该新方法完全避免了在此反应中使用有机酸和有毒或昂贵的溶剂。催化剂无废弃物产生,易于制备,并可高效重复使用。
