  Discovery of a novel indole series of EP1 receptor antagonists by scaffold hopping

  摘要：

  We describe the medicinal chemistry approach that generated a novel indole series of EP1 receptor antagonists. The SAR of this new template was evaluated and culminated in the identification of compound 12g which demonstrated in vivo efficacy in a preclinical model of inflammatory pain. (C) 2008 Elsevier Ltd.

• Towards the syntheses of<i>N</i>-H and<i>N</i>-alkylated derivatives of meridianins

  Novel N-H and N-alkylated derivatives of meridianins have been synthesized as potential antitumor agents by a two-step conversion of N-tosyl-3-acetylindoles or N-alkyl-3-acetylindoles to the corresponding enaminones using DMF-DMA, with or without added pyrrolidine. Further cyclization with guanidine gave the corresponding 2-aminopyrimidines. The structures of the compounds, thus obtained, were proved

  通过使用DMF-DMA将N-甲苯磺酰基-3-乙酰基吲哚或N-烷基-3-乙酰基吲哚经两步转化为相应的烯胺酮，合成了经络胺的新型N- H和N-烷基化衍生物作为潜在的抗肿瘤药。或不添加吡咯烷。用胍进一步环化得到相应的2-氨基嘧啶。由此获得的化合物的结构通过1 H和13 C NMR光谱，NOE实验和X射线分析证明。

  Rh(III)catalyzed general strategy was developed for the site selective remote C4 (sp2) and C2 (sp3)-methyl thiolation of indole core keeping the oxime directing group at the C3 position. The transformation was accomplished under mild conditions with wide scope and functional group tolerance. The directing group can easily be removed after operation. Methyl substitution at the C2 position of indole core

  一种直接的Rh（III）催化的一般策略是针对吲哚核的位点选择性远程C4（sp 2）和C2（sp 3）-甲基硫醇化而开发的，将肟导向基团保持在C3位置。该转化是在温和条件下完成的，具有宽范围和官能团耐受性。引导组可以在操作后轻松移除。吲哚核的C2位置处的甲基取代导致C2（sp 3）-甲基硫醇化。
• Rhodium(III)-Catalyzed Regioselective Direct C4-Alkylation and C2-Annulation of Indoles: Straightforward Access to Indolopyridone
  作者：Aniruddha Biswas、Rajarshi Samanta

  日期：2018.3.29

  C4‐alkylation and C2‐annulation of indole derivative has been developed by using variable diazo esters. Fine tuning of the reactivity of diazo esters leads to control in regioselectivity with wide scope and functional‐group tolerance. A straightforward approach has been established to furnish an indolopyridone scaffold.

  Novel and efficient Mn(OAc)3⋅2H2O promoted radical addition-[4 + 1] cyclization relay of 3-indolymethanols and phosphites was disclosed, which afforded 1,2-oxaphospholoindole derivatives in moderate to good yields. Based on the experimental and computational studies, a mechanism involving radical addition and intramolecular cyclization cascade was proposed.

  have been developed. The former route enables C4-arylation in a highly efficient and mild manner and the latter route provides an alternative straightforward protocol for synthesis of C2/C4 disubstituted indoles. The mechanism studies imply that the different reaction pathways were tuned by the distinct acid additives, which led to either the Pd(I)–Pd(II) pathway or Pd(II) catalysis.

  吲哚的高效 C4-芳基化和多米诺 C4-芳基化/3,2-羰基迁移已经开发出来。前一种路线能够以高效且温和的方式实现C4-芳基化，后一种路线为合成C2/C4二取代吲哚提供了一种替代的简单方案。机理研究表明不同的反应途径是通过不同的酸添加剂调节的，从而导致 Pd()–Pd( II ) 途径或 Pd( II ) 催化。
