  2-Arylindoles as gonadotropin releasing hormone (GnRH) antagonists: optimization of the tryptamine side chain

  摘要：

  A series of 2-arylindoles containing novel heteroaromatic substituents on the tryptamine tether, based on compound 1, was prepared and evaluated for their ability to act as gonadotropin releasing hormone (GnRH) antagonists. Successful modifications of 1 included chain length variation (reduction) and replacement of the pyridine with heteroaromatic groups. These alterations culminated in the discovery of compound 27kk which had excellent in vitro potency and oral efficacy in rodents. (C) 2002 Elsevier Science Ltd. All rights reserved.

• Zinc‐Catalysed N‐Iodosuccinimide‐Enabled Selective N2‐Olefination of Benzotriazoles with Alkenes

  Herein, we describe a zinc‐catalysed N2‐selective olefination of benzotriazoles with unactivated alkenes and styrenes. The transformation is achieved by a N‐iodosuccinimide (NIS)‐mediated two‐step, one‐pot approach, proceeding through sequential regioselective β‐iodoalkylation of benzotriazoles with alkenes and a subsequent base‐promoted 1,2‐elimination. The N2‐selective β‐iodoalkylation of benzotriazoles

  在本文中，我们描述了苯并三唑与未活化的烯烃和苯乙烯的锌催化N 2选择性烯化反应。该转化是通过N碘代琥珀酰亚胺（NIS）介导的两步一锅法完成的，该方法通过依次进行苯并三唑与烯烃的区域选择性β碘烷基化和随后的碱促进的1,2消除。苯并三唑的N 2选择性β碘烷基化具有高度立体定向性，可在非常简单温和的条件下发挥作用，表现出出色的官能团耐受性。N 2的高选择性归因于N之间的分子间氢键碘代琥珀酰亚胺和苯并三唑的1位上的NH氢键供体。这种可扩展的过程，作为结构多样的N 2烯烃化苯并三唑的模块化组装的有效方法，将极大地促进苯并三唑的N 2功能化的化学反应。

  An original approach to achieve the C(sp2)–H azolation of cyclic aldonitrones mediated by Selectfluor® has first been employed. By exploiting a metal-free, visible-light-promoted cross-dehydrogenative C–N coupling reaction between model aldonitrones, 2H-imidazole 1-oxides, and NH-containing azoles, a series of novel azaheterocyclic derivatives have been obtained in yields up to 94%.
