• Phenazinium Salt-Catalyzed Aerobic Oxidative Amidation of Aromatic Aldehydes
  作者：Dasheng Leow

  DOI：10.1021/ol5029354

  日期：2014.11.7

  Amides are prevalent in organic synthesis. Developing an efficient synthesis that avoids expensive oxidants and heating is highly desirable. Here the oxidative amidation of aromatic aldehydes is reported using an inexpensive metal-free visible light photocatalyst, phenazine ethosulfate, at low catalytic loading (1–2 mol %). The reaction proceeds at ambient temperature and uses air as the sole oxidant

  A novel and efficient protocol for the synthesis of amides is reported which employs a BODIPY catalyzed oxidative amidation reaction between aromatic aldehydes and amines under visible light. Compared with the known Ru or Ir molecular catalysts and other organic dyes, the BODIPY catalyst showed higher reactivity toward this reaction. Mechanistic studies reveal that dioxygen could be activated through

  作者：Ling Xu、Shuai‐Zheng Zhang、Wei Li、Zhan‐Hui Zhang

  DOI：10.1002/chem.202005138

  SEM, TEM, energy‐dispersive X‐ray spectroscopy, and vibrating‐sample magnetometer techniques. Fe3O4/PDA/CdS was found to be a highly active photocatalyst for the amidation of aromatic aldehydes by using air as a clean oxidant under mild conditions. The photocatalyst can be recovered by magnetic separation and successfully reused for five cycles without considerable loss of its catalytic activity.

  reductive alkylation reactions of amines using carboxylic acids as nominal electrophiles. The two-step reaction exploits the dual reactivity of phenylsilane and involves a silane-mediated amidation followed by a Zn(OAc)2-catalyzed amide reduction. The reaction is applicable to a wide range of amines and carboxylic acids and has been demonstrated on a large scale (305 mmol of amine). The rate differential between

  我们报道了使用羧酸作为标称亲电子试剂的胺的还原烷基化反应。该两步反应利用了苯基硅烷的双重反应性，涉及硅烷介导的酰胺化，然后是 Zn(OAc) 2催化的酰胺还原。该反应适用于多种胺和羧酸，并已得到大规模证明（305 mmol 胺）。抗逆转录病毒药物马拉韦罗的聚合合成中体现了叔酰胺中间体和仲酰胺中间体的还原速率差异。机理研究表明，酰胺化步骤中残留的 0.5 当量羧酸负责生成具有增强反应性的硅烷还原剂，从而可以还原以前在锌/苯基硅烷体系中不反应的仲酰胺。
