  • Identification of Phenylpyrazolone Dimers as a New Class of Anti‐ <i>Trypanosoma cruzi</i> Agents
    作者:Maarten Sijm、Julianna Siciliano de Araújo、Alba Ramos Llorca、Kristina Orrling、Lydia Stiny、An Matheeussen、Louis Maes、Iwan J. P. Esch、Maria Nazaré Correia Soeiro、Geert Jan Sterk、Rob Leurs

    日期:2019.9.18
    library led to the identification of 2,2′‐methylenebis(5‐(4‐bromophenyl)‐4,4‐dimethyl‐2,4‐dihydro‐3H‐pyrazol‐3‐one), a phenyldihydropyrazolone dimer, which shows an in vitro pIC50 value of 5.4 against Trypanosoma cruzi. Initial optimization was done by varying substituents of the phenyl ring, after which attempts were made to replace the phenyl ring. Finally, the linker between the dimer units was varied
    查加斯病正在成为一个世界性问题;目前估计超过六百万人受到感染。目前使用的两种药物,苯并硝唑和硝呋莫司,需要长期治疗方案,在慢性感染阶段疗效有限,并且已知会引起不良反应。对内部文库进行表型筛选,鉴定出 2,2'-亚甲基双(5-(4-溴苯基)-4,4-二甲基-2,4-二氢-3 H-吡唑-3-酮),苯基二氢吡唑啉酮二聚体,其针对克氏锥虫的体外 pIC 50值为 5.4 。最初的优化是通过改变苯环的取代基来完成的,之后尝试替换苯环。最后,二聚体单元之间的连接体发生变化,最终形成 2,2'-亚甲基双(5-(3-溴-4-甲氧基苯基)-4,4-二甲基-2,4-二氢-3 H-吡唑- 3-one (NPD-0228) 是最有效的类似物。NPD-0228 对T. cruzi细胞内无鞭毛体的体外 pIC 50值为 6.4 ,对人 MRC-5 细胞系和小鼠心肌细胞没有明显毒性。
  • Gallium Trihalide Catalyzed Sequential Addition of Two Different Carbon Nucleophiles to Esters by Using Silyl Cyanide and Ketene Silyl Acetals
    作者:Yoshihiro Inamoto、Yuta Kaga、Yoshihiro Nishimoto、Makoto Yasuda、Akio Baba
    DOI:10.1002/chem.201403734
    日期:2014.9.8
    sequential addition of silyl cyanide and ketene silyl acetals to esters was achieved by a gallium trihalide catalyst to produce β‐cyano‐β‐siloxy esters. This is the first example of the sequential addition of two different carbon nucleophiles to esters. The employment of lactones provided α,α‐disubstituted cyclic ethers with a cyano group and an ester moiety. A variety of esters and lactones are applicable
    通过三卤化镓催化剂可将甲硅烷基氰化物和乙烯酮甲硅烷基缩醛顺序添加到酯中,以生产β-氰基-β-甲硅烷氧基酯。这是将两个不同的碳亲核试剂顺序加成到酯中的第一个例子。内酯的使用为α,α-二取代的环状醚提供了一个氰基和一个酯基。多种酯和内酯可用于该反应系统。
  • Indium Tribromide Catalyzed Cross-Claisen Condensation between Carboxylic Acids and Ketene Silyl Acetals Using Alkoxyhydrosilanes
    作者:Yoshihiro Nishimoto、Aya Okita、Makoto Yasuda、Akio Baba
    DOI:10.1002/anie.201104140
    日期:2011.9.5
    Acylations achieved: The title reaction between carboxylic acids and ketene silyl acetals has been accomplished (see scheme). The additive, (MeO)3SiH, is believed to play an important role in the promotion of the condensation reaction. This reaction system was compatible with a diverse range of functional groups, including alkenes, alkynes, chlorides, alcohols, esters, and nitro groups.
    达到的酰化作用:羧酸与乙烯酮甲硅烷基缩醛之间的标题反应已经完成(参见方案)。据信添加剂(MeO)3 SiH在促进缩合反应中起重要作用。该反应体系可与多种官能团兼容,包括烯烃,炔烃,氯化物,醇,酯和硝基。
  • A Synthesis of α,α-Disubstituted Aryl-β-ketoesters
    作者:Mark Stefaniak、Fabrice Tinardon、John Wallis
    DOI:10.1055/s-1997-3249
    日期:1997.6
    applicable synthesis of alpha,alpha-disubstituted beta-ketoesters involving reaction of a substituted benzoyl chloride with methyl trimethylsilyl ketene acetal is described. Addition of boron trifluoride etherate is essential when the benzoyl chloride is nor substituted with a strongly electron withdrawing residue. The majority of experiments were conducted with the dimethylketene acetal but the process
    描述了一种普遍适用的 α,α-二取代 β-酮酯合成,包括取代苯甲酰氯与甲基三甲基甲硅烷基乙烯酮缩醛的反应。当苯甲酰氯未被强吸电子残基取代时,添加三氟化硼醚合物是必不可少的。大多数实验是用二甲基乙烯酮缩醛进行的,但该过程同样适用于环己烷乙烯酮缩醛 5。
  • Metal-Free Catalytic Reduction of α,β-Unsaturated Esters by 1,3,2-Diazaphospholene and Subsequent C–C Coupling with Nitriles
    作者:Che Chang Chong、Bin Rao、Rei Kinjo
    DOI:10.1021/acscatal.7b01338
    日期:2017.9.1
    tautomerizes to saturated esters, while the P–O bond cleavage by HBpin via a formal σ-bond metathesis affords boryl enolate intermediate. The latter could undergo a further coupling reaction with nitriles to form substituted amino diesters or 1,3-imino esters, depending on α,β-unsaturated ester substrates. These catalytic reactions can also be performed in a one-pot manner, illustrating a protocol for metal-free
    1,3,2-二氮杂磷腈1催化α,β-不饱和酯的共轭转移氢化以及1,4-氢硼化。两种方法的起始步骤都包括α,β-不饱和酯的1,4-氢磷酸化,以得到次膦酰基烯醇醚。氨硼烷随后切断了次膦酰基烯醇醚中的P–O键(AB)生成一个互变异构体成饱和酯的烯醇中间体,而HBpin通过正式的σ键复分解通过HB的P–O键裂解,提供了烯醇硼酸酯中间体。取决于α,β-不饱和酯底物,后者可与腈进一步进行偶联反应以形成取代的氨基二酯或1,3-亚氨基酯。这些催化反应也可以一锅法进行,说明了无金属催化C-C键构建的方案。
