• Aerobic Oxidative Cross-Coupling of Substituted Acrylamides with Alkenes Catalyzed by an Electron-Deficient CpRh^III Complex
  作者：Ryo Yoshimura、Yu Shibata、Ken Tanaka

  DOI：10.1021/acs.joc.9b01733

  日期：2019.10.18

  It has been established that an electron-deficient CpRhIII complex, bearing two ester moieties on the Cp ring, [CpERhIII], catalyzes the aerobic oxidative cross coupling of substituted acrylamides with both activated and unactivated alkenes, leading to (2Z,4E)-dienamides, at relatively low temperature (80 °C). Importantly, tertiary, secondary, and primary amide directing groups could equally be used

  已经确定，在Cp环上带有两个酯部分的缺电子CpRhIII络合物[CpERhIII]催化取代的丙烯酰胺与活化和未活化烯烃的需氧氧化交叉偶联，从而生成（2Z，4E）-二酰胺，温度较低（80°C）。重要的是，叔，仲和伯酰胺导向基团同样可以用于该催化中。机理研究表明，CpERhIII配合物的电子缺陷性质促进了丙烯酰胺的限制营业额的乙烯基CH键裂解。
• Asymmetric Dihydroxylation of Esters and Amides of Methacrylic, Tiglic, and Angelic Acid: No Exception to the Sharpless Mnemonic!
  作者：Fabian Weber、Reinhard Brückner

  日期：2015.4

  are contradictory and partly in conflict with the Sharpless mnemonic. We systematically screened the SAD of esters and amides of angelic, tiglic, and methacrylic acid. Enantiocontrol arose in 14 of the 15 reactions, culminating at 99 % ee for the Weinreb amide of tiglic acid. The absolute configurations of all the nonracemic products were established by (stereo)chemical correlations. Without exception

  关于当归酸异丁酯的 Sharpless 不对称二羟基化 (SAD) 面部选择性的文献发现是矛盾的，部分与 Sharpless 助记符相冲突。我们系统地筛选了当归、tiglic 和甲基丙烯酸的酯和酰胺的 SAD。在 15 个反应中的 14 个反应中出现了对映体控制，在 tiglic acid 的 Weinreb 酰胺的 ee 达到 99% 时达到顶峰。所有非外消旋产物的绝对构型都是通过（立体）化学相关性建立的。无一例外，它们都符合 Sharpless 助记符。

  Bismaleimides (BMI) exhibit excellent heat resistance (high Tg and high resistance to thermal decomposition) compared to epoxy resins and phenolic resins, and therefore, in recent years, more attention is paid to bismaleimides as a resin material for the next-generation devices represented by SiC power semiconductors, in addition to the investigation on the use of bismaleimides for electronic material applications. As such, conventional BMI's are known as highly heat-resistant resins; however, there is a demand for a resin having higher heat resistance for advanced material applications and the like. Thus, an object of the invention is to provide a novel maleimide compound having superior heat resistance. Disclosed is a substituted or unsubstituted allyl group-containing maleimide compound having a structure with three or more benzene rings, having one or more groups each having a substituted or unsubstituted allyl group, and having one or more maleimide groups.

  A synergistic catalytic method combining photoredox catalysis, hydrogen‐atom transfer, and proton‐reduction catalysis for the dehydrogenative silylation of alkenes was developed. With this approach, a highly concise route to substituted allylsilanes has been achieved under very mild reaction conditions without using oxidants. This transformation features good to excellent yields, operational simplicity

  unactivated alkenes via vinylic C–H activation has been developed. The present cross-coupling reaction was examined with a variety of differently functionalized acrylamides and unactivated olefins. In these reactions, highly valuable amide-functionalized butadienes were prepared in good to excellent yields. This protocol was also compatible with Weinreb amides. A possible reaction mechanism involving the chelation-assisted
