  A Comparison of Catalysts to Promote Imidazolide Couplings Including the Identification of 2-Hydroxy-5-nitropyridine as a New, Safe, and Effective Catalyst

  摘要：

  Five catalysts were compared with respect to their safety and catalytic effectiveness for promoting imidazolide couplings, Reaction rate enhancement, shock sensitivity, and differential scanning calorimetry (DSC) data were considered in this analysis. 6-Chloro-1-hydroxybenzotriazole, which has been described in the literature as a safe catalyst, was found to be shock sensitive. 2-Hydroxy-5-nitropyridine is a new catalyst for this type of reaction and was found to be safe, effective, readily available, and similar in price to that of the 1-hydroxybenzotriazole, a common catalyst for promoting acylation reactions.

  Challenging couplings of hindered carboxylic acids with non-nucleophilic amines to form amide bonds can be accomplished in high yields, and in many cases, with complete retention of the adjacent stereogenic centers using the combination of N,N,N′,N′-tetramethylchloroformamidinium hexafluorophosphate (TCFH) and N-methylimidazole (NMI). This method allows for in situ generation of highly reactive acyl imidazolium

  具有挑战性的受阻羧酸与非亲核胺形成酰胺键的偶联可以高收率完成，而且在许多情况下，使用N，N，N '，N'-四甲基氯甲ami的组合完全保留相邻的立体异构中心六氟磷酸盐（TCFH）和N-甲基咪唑（NMI）。该方法允许原位产生高反应性的酰基咪唑鎓离子，其已被证明是反应的中间体。该试剂具有类似于酰基氯的高反应活性，并且易于使用现代铀试剂。

  A highly efficient intramolecular selective aryl migration/desulfonylation of 2-bromo-N-aryl-N-(arenesulfonyl)amide via visible light-induced photoredox catalysis has been accomplished. This approach allows for the construction of a variety of multisubstituted N,2-diarylacetamide under mild reaction conditions.

  Hydroaminocarbonylation of alkenes is one of the most promising yet challenging methods for the synthesis of amides. Herein, we reported the development of a novel and effective Pd-catalyzed Markovnikov hydroaminocarbonylation of 1,1-disubstituted or 1,1,2-trisubstituted alkenes with aniline hydrochloride salts to afford amides bearing an α quaternary carbon. The reaction makes use of readily available

  烯烃的氢氨基羰基化是合成酰胺最有前途但最具挑战性的方法之一。在此，我们报道了一种新型且有效的 Pd 催化 Markovnikov 氢氨基羰基化反应的 1,1-二取代或 1,1,2-三取代烯烃与苯胺盐酸盐的反应，以提供带有 α 季碳的酰胺。该反应利用容易获得的起始材料，耐受范围广泛的官能团，并为各种带有 α 季碳的酰胺提供了一种简便而直接的方法。机理研究表明该反应通过氢化钯途径进行。氢化钯和 CO 插入是可逆的，氨解可能是限速步骤。

  1,8-Diazabicyclo[5.4.0]undec-7-ene (DBU) has been found to catalyze the amidation of acyl Imidazoles. The rate acceleration is especially evident with traditionally unreactive, electron-deficient anilines. DBU is readily available and offers safety and cost advantages over more commonly employed catalysts such as 1-hydroxybenzotriazole.
