• Iminyl-radicals by electrochemical decarboxylation of α-imino-oxy acids: construction of indole-fused polycyclics
  作者：Jin-Lin Wan、Jian-Feng Cui、Wei-Qiang Zhong、Jing-Mei Huang

  DOI：10.1039/d1cc03891e

  日期：——

  Iminyl radicals are reactive intermediates that can be used for the construction of various valuable heterocycles. Herein, the electrochemical decarboxylation of α-imino-oxy acids for the generation of iminyl radicals has been accomplished under exogenous-oxidant- and metal-free conditions through the use of nBu4NBr as a mediator. The resulting iminyl radicals undergo intramolecular cyclization smoothly

  Nitrogen-containing heterocycles are prevalent in both naturally and synthetically bioactive molecules. We report herein an unprecedented protocol for radical aza-cyclization of α-imino-oxy acids with pendant alkenes via synergistic photoredox and cobaloxime catalysis. With or without alkenes as the intermolecular cross-coupling partners, the transformation provides a variety of corresponding alkene-containing dihydropyrrole

  作者：Han Seul Park、Zhoulong Fan、Ru‐Yi Zhu、Jin‐Quan Yu

  日期：2020.7.27

  Reported herein is the distal γ‐C(sp3)−H olefination of ketone derivatives and free carboxylic acids. Fine tuning of a previously reported imino‐acid directing group and using the ligand combination of a mono‐N‐protected amino acid (MPAA) and an electron‐deficient 2‐pyridone were critical for the γ‐C(sp3)−H olefination of ketone substrates. In addition, MPAAs enabled the γ‐C(sp3)−H olefination of free carboxylic

  本文报道了酮衍生物和游离羧酸的远端γ-C(sp 3 )-H烯化。微调先前报道的亚氨基酸导向基团并使用单N保护氨基酸（MPAA）和缺电子2-吡啶酮的配体组合对于γ-C(sp 3 )-H烯化至关重要酮底物。此外，MPAA 能够使游离羧酸发生 γ-C(sp 3 )-H 烯化反应，形成多种六元内酯。除了烷基羧酸之外，苄基 C(sp 3 )−H 键也可以通过 2-甲基苯甲酸衍生物一步功能化形成 3,4-二氢异香豆素结构。这些方案的实用性在大规模反应和 γ-C(sp 3 )−H 烯化产物的多样化中得到了证明。
