• Electrochemical Synthesis of (Aza)indolines<i>via</i>Dehydrogenative [3+2] Annulation: Application to Total Synthesis of (±)-Hinckdentine A
  作者：Zhong-Wei Hou、Hong Yan、Jin-Shuai Song、Hai-Chao Xu

  DOI：10.1002/cjoc.201800301

  日期：2018.10

  An electrochemical synthesis of functionalized (aza)indolines through dehydrogenative [3+2] annulation of arylamines with tethered alkenes has been developed. Previous reported syntheses through similar inter‐ and intramolecular annulation reactions required noble‐metal catalysts and are mostly limited to terminal alkenes or 1,3‐dienes. The electrosynthesis employs the easily available and inexpensive

  已经开发了通过芳胺与链状烯烃的脱氢[3 + 2]环合进行官能化（氮杂）二氢吲哚的电化学合成方法。先前报道的通过类似的分子间和分子内环化反应进行的合成需要贵金属催化剂，并且大多限于末端烯烃或1,3-二烯。电合成采用容易获得且便宜的二茂铁作为分子催化剂，并与二，三，甚至四取代的烯烃相容，以构建二氢吲哚以及更具挑战性的氮杂二氢吲哚。利用新开发的电合成作为关键步骤，已从市售材料中分12个步骤（最长的线性序列）完成了海洋生物碱（±）-扁桃碱A的全合成。
• Synthesis of arylbromides from arenes and <i>N</i>-bromosuccinimide (NBS) in acetonitrile — A convenient method for aromatic bromination
  作者：Eli Zysman-Colman、Karla Arias、Jay S. Siegel

  DOI：10.1139/v08-176

  日期：2009.2

  Regioselective and chemoselective electrophilic bromination of a wide series of activated arenes using N-bromosuccinimide (NBS) in acetonitrile occurs readily. Environmentally friendly conditions, large substrate scope, and ease of synthesis enhance the utility of this method over other electrophilic bromination conditions.

  利用乙腈中的 N-溴代丁二酰亚胺（NBS），可以很容易地对一系列活化的炔类化合物进行区域选择性和化学选择性亲电溴化反应。与其他亲电溴化条件相比，该方法的环境友好、底物范围大且易于合成，从而提高了其实用性。
