  Cinnamic acid and its derivatives are known for anti-tubercular activity. The present study reports the synthesis of cinnamic acid derivatives via bioisosteric replacement of terminal carboxylic acid with "oxadiazole". A series of cinnamic acid derivatives (styryl oxadiazoles) were designed and synthesized in good yields by reaction of substituted cinnamic acids (2, 15a-15s) with amidoximes. The synthesized

  肉桂酸及其衍生物具有抗结核活性。本研究报道了通过用“恶二唑”对末端羧酸进行生物等位取代来合成肉桂酸衍生物。通过取代肉桂酸（2，15a-15s）与a肟的反应，设计并合成了一系列肉桂酸衍生物（苯乙烯基恶二唑），并以高收率合成。体外评估了合成的苯乙烯基恶二唑类药物对结核分枝杆菌（Mtb）H37Ra菌株的抗结核活性。结构-活性关系（SAR）研究确定了几种具有混合抗结核特性的化合物。化合物32显示出有效的抗结核活性（IC50 = 0.045 µg / mL）。

  Thiocyanate compounds are key intermediates in the synthesis of pharmaceuticals and other sulfur-containing organic compounds. Herein, we first report an electrochemical protocol to synthesize vinyl thiocyanates from decarboxylative coupling of cinnamic acids with NH4SCN in aqueous solution. This method provides thiocyanation products with broad functional group tolerance under ambient conditions.

• Nucleophile-Selective Cross-Coupling Reactions with Vinyl and Alkynyl Bromides on a Dinucleophilic Aromatic Substrate

  日期：2015.4

  A nucleophile-selective cross-coupling reaction on an aromatic compound bearing two metal groups, Bpin and SnMe3, has been developed. Previously, only aryl bromides and iodides could be used as electrophilic components, but in this work, the scope could be extended to vinyl and alkynyl bromides as electrophiles. This means that the roles typical in Sonogashira couplings or Heck reactions of the aromatic

  已经开发了对带有两个金属基团 Bpin 和 SnMe3 的芳香族化合物的亲核试剂选择性交叉偶联反应。以前，只有芳基溴化物和碘化物可以用作亲电组分，但在这项工作中，范围可以扩展到乙烯基和炔基溴化物作为亲电试剂。这意味着芳香环的 Sonogashira 偶联或 Heck 反应中作为与乙烯基和炔基金属物种的介电偶联的典型作用被颠倒了，这为有机合成提供了一种新工具。第一个反应的亲核位点是甲锡烷基，随后，铃木-宫浦交叉偶联反应可以在同一分子上发生。
• Pd-Catalyzed Difluoromethylation of Vinyl Bromides, Triflates, Tosylates, and Nonaflates
  作者：Dalu Chang、Yang Gu、Qilong Shen

  DOI：10.1002/chem.201500551

  日期：2015.4.13

  Pd‐catalyzed difluoromethylation of di‐, tri‐ or tetra‐substituted vinyl bromides, triflates, tosylates and nonaflates under mild conditions is described. The reaction tolerates a wide range of functional groups, such as bromide, chloride, fluoride, ester, amine, nitrile, and protected carbonyl, thus providing a general route for the preparation of difluoromethylated alkenes.

  描述了在温和条件下二，三或四取代乙烯基溴，三氟甲磺酸酯，甲苯磺酸酯和壬二酸酯的钯催化二氟甲基化。该反应可耐受各种官能团，例如溴化物，氯化物，氟化物，酯，胺，腈和受保护的羰基，因此提供了制备二氟甲基化烯烃的一般途径。
