• Palladium-Catalyzed Denitrative α-Arylation of Ketones with Nitroarenes
  作者：Zhirong Li、Yonggang Peng、Tao Wu

  DOI：10.1021/acs.orglett.0c04104

  日期：2021.2.5

  The palladium-catalyzed α-arylation of ketones with readily available nitroarenes and nitroheteroarenes provides access to useful α-aryl and α-heteroaryl ketones. The use of the Pd/BrettPhos catalysts was critical to achieve high efficiency for these transformations, whereas other catalysts led to decreased yields or no conversions. The intramolecular type substrate was also applied in this methodology

  钯催化α -用容易获得的硝基芳烃和芳基化nitroheteroarenes酮的提供访问有用的α -芳基和α -杂芳基酮。Pd / BrettPhos催化剂的使用对于实现这些转化的高效率至关重要，而其他催化剂则导致收率降低或没有转化。分子内型底物也用于该方法中，得到色酮衍生物。聚芳族羰基化合物可以通过多组分串联反应而容易地获得，经由亲核芳族取代（S Ñ AR）或交叉偶联反应，接着此denitrative芳基化。动力学实验表明，硝基苯的电子效应比酮的电子效应对反应速率的影响更大。

  An application of the PIFA-mediated [PIFA: phenyliodine(III) bis(trifluoroacetate)] biaryl coupling reaction is presented and extended to the formation of heterobiaryl connections. A preliminary study of the scope and limitations of this procedure was carried out in the synthesis of phenanthroids 11 from a series of phenethyl-substituted heterocycles 10. It was observed that in some cases a competitive

  amides and highly reactive organometallic reagents bring great challenges for an efficient and selective synthetic approach. Herein, we reported an lithium diisopropylamide (LDA)-promoted benzylic aroylation of toluenes with unactivated tertiary benzamides, providing a direct and efficient synthesis of various aryl benzyl ketones. This process features a kinetic deprotonative functionalization of toluenes

  甲苯的去质子官能化，由于酸性较弱，一般需要强碱，因此条件要求苛刻，会产生副产物。酰胺与有机金属试剂的直接亲核酰基取代反应可以为酮合成提供理想的解决方案。然而，惰性酰胺和高反应性有机金属试剂为高效和选择性的合成方法带来了巨大挑战。在此，我们报道了二异丙基酰胺锂 (LDA) 促进的甲苯与未活化的叔苯甲酰胺的苄基芳酰化，提供了各种芳基苄基酮的直接有效合成。该过程具有甲苯的动力学去质子官能化和易于获得的基础 LDA。机制研究表明，定向叔苯甲酰胺与 LDA 的邻位锂化促进了甲苯的苄基动力学去质子化，并引发了与酰胺的亲核酰基取代反应。

  The intramolecular Friedel-Crafts acylation of 4,5-diarylpentanoic acids has the possibility to cyclise to either a 6-membered ring to give 4-benzyltetral-1-one or a 7-membered ring to give 4-arylbenzosuber-1-one. Of these, only the former compound class has previously been reported. The impact of the substituents positioning on the outcome of the cyclisation has been investigated. The complete formation
