  摘要：

  在Selectfluor的存在下，钯（II）催化剂可将伯酰胺高效且化学选择性地转化为腈。酰胺可以连接到芳环，杂芳环或脂族侧链上，并且该反应可耐受空间体积和电子修饰。含有三个谷氨酰胺基团的肽醇的脱水为每个谷氨酰胺残基提供了构效关系。因此，这种脱水可以通过合成突变与谷氨酰胺的丙氨酸扫描相似。

  The rearrangement of aldoximes to primary amides has been studied using the readily available arene-ruthenium(II) complex [RuCl2(η6-C6Me6)P(NMe2)3}] (5 mol %) as catalyst. Reactions proceeded cleanly in pure water at 100 °C without the assistance of any cocatalyst, affording the desired amides in high yields (70–90%) after short reaction times (1–7 h). The process was operative with both aromatic

  醛肟于伯酰胺的重排已使用容易获得的芳烃-钌（II）络合物将[RuCl研究2（η 6 -C 6我6）P（NME 2）3 }]（5摩尔％）作为催化剂。反应在纯水中于100°C干净地进行，无需任何助催化剂的帮助，在较短的反应时间（1-7小时）后，以高收率（70-90％）得到所需的酰胺。该方法对芳香族，杂芳香族，α，β-不饱和和脂肪族醛肟均有效，并能耐受多个官能团。使用18的反应曲线和实验O标记的水表明在这些转化中涉及两种不同的机制。在两者中，腈中间体最初都是通过醛肟的脱水而形成的。然后通过醛肟或水的第二分子的作用将这些中间体水合为相应的酰胺。还讨论了苯甲醛肟重排成苯甲酰胺的动力学分析。

Especially, compound 5n, exhibited better fungicidal activities than the commercial fungicide flutolanil against two tested fungi Valsa mali and Sclerotinia sclerotiorum, with EC50 values of 3.44 and 2.63 mg/L, respectively. And it also displayed good in vivo fungicidal activity against

  Diflumetorim is a member of pyrimidinamine fungicides that possess excellent antifungal activities. Nevertheless, as reported that the activity of diflumetorim to corn rust (Puccinia sorghi) was not ideal (EC50 = 53.26 mg/L). Herein, a series of novel pyrimidinamine derivatives containing phenyl-thiazole/oxazole moiety were designed based on our previous study and the structural characteristics of

  地氟美林是嘧啶胺杀菌剂的成员，具有优异的抗真菌活性。然而，据报道，双氟甲蝶呤对玉米锈病（高粱）的活性并不理想（EC50 = 53.26 mg / L）。在此，根据我们先前的研究和双氟甲草胺的结构特征，设计合成了一系列含有苯基-噻唑/恶唑部分的新型嘧啶胺衍生物，并对其进行了生物测定并进行了生物测定，以发现具有优异抗真菌活性的新型杀菌剂。在这些化合物中，T18具有最佳的杀真菌活性，分别对高粱P.orghi和E. graminis的EC50值为0.93 mg / L和1.24 mg / L，具有明显优于商业杀真菌剂diflumetorim，tebuconazole和flusilazole的防治效果。细胞的细胞毒性结果表明，化合物T18的毒性低于双氟甲蝶呤。此外，DFT计算表明，苯基噻唑/恶唑部分在活性提高中起着不可争辩的作用，这将有助于将来设计和开发更有效的化合物。

  作者：Akira Yoshimura、Matthew W. Luedtke、Viktor V. Zhdankin

  日期：2012.2.17

  A new, mild procedure for the Hofmann rearrangement of aromatic and aliphatic carboxamides using (tosylimino)phenyl-λ3-iodane, PhINTs, as a reagent is reported. Because of the mild reaction conditions, this method is particularly useful for the Hofmann rearrangement of substituted benzamides, which usually afford complex reaction mixtures with other hypervalent iodine oxidants. The mild reaction conditions

  一种新的，温和的程序使用（tosylimino）苯基-λ芳香族和脂肪族羧酰胺的霍夫曼重排3 -iodane，PhINTs，作为试剂被报告。由于反应条件温和，该方法对于取代的苯甲酰胺的霍夫曼重排特别有用，该苯甲酰胺通常会提供与其他高价碘氧化剂的复杂反应混合物。羧酰胺与PhINTs反应的温和反应条件和高选择性可以分离最初形成的不稳定异氰酸酯，或通过用醇处理将其随后转化为稳定的氨基甲酸酯。

  A series of novel 2,4,5-trisubstituted 1,3-thiazole derivatives containing hydrazide–hydrazine, and carboxamide moiety including 46 compounds T were synthesized, and evaluated for their antitumor activity in vitro against a panel of five human cancer cell lines. Eighteen title compounds T displayed higher inhibitory activity than that of 5-Fu against MCF-7, HepG2, BGC-823, Hela, and A549 cell lines
