  Indole amide derivatives: synthesis, structure–activity relationships and molecular modelling studies of a new series of histamine H1-receptor antagonists

  摘要：

  A number of indole amide derivatives bearing a basic side chain, in which the indole ring replaces the isoster benzimidazole nucleus typical of some well-known antihistamines, were prepared and tested for their H-1-antihistaminic activity. The 1-benzyl-3-indolecarboxamides 32-42 showed antihistaminic (H-1) activity (pA(2) 6-8); the 3-indolylglyoxylylamides 7-16 and the 2-indolecarboxamides 48-56 showed little or no activity. Insertion of the basic side chain of the active 3-indolecarboxamide derivatives into a piperazine ring (compounds 57-59) led to a dramatic loss of activity. All the active compounds proved to be competitive antagonists, since the values of the regression slope were not statistically different from 1. The most active compounds, 32, 33, 38-41, were also tested both in vitro for their anticholinergic activity and in vivo for their ability to antagonize histamine-induced cutaneous vascular permeability in rats. The biological results and the structure-activity relationships of the novel compounds are discussed in the light of molecular modelling studies, taking the molecule of astemizole as a model, and referring to proposed H-1-receptor pharmacophore models.

  镍(II)催化吲哚与供体-受体环丙烷之间的形式[3+2]环加成反应

  摘要：

  本文描述了镍催化的区域和非对映选择性形式 [3+2] 环加成反应，N-取代吲哚和供体-受体环丙烷之间的加成反应，以合成环戊[b]吲哚。优化的反应条件提供了所需的含氮环加合物，产率高达 93%，dr 为 8.6:1，具有完全的区域选择性。该底物范围对各种取代的吲哚和环丙烷表现出高度耐受性，从而合成了六种新的环戊二烯[b]吲哚，并分离了文献中报道的五种衍生物。此外，通过 ESI-MS 在线反应监测研究了该反应的机理建议，从而可以识别 Ni(II) 催化过程中的反应中间体。 X射线晶体学证实了产物的结构和相关内切立体化学。该方法能够从容易获得的起始材料快速有效地构建稠合二氢吲哚。

  The fellowship of the rings: The previously undiscovered ability of indole‐derived donor–acceptor cyclopropanes to involve four reaction centers simultaneously was revealed by their domino cyclodimerization (see scheme). This SnCl4‐induced reaction affords bisindole products with the pentaleno[1,6‐a,b]indole framework. In the course of this process, two new rings, three CC bonds, and four stereocenters

  环的团契：以前未被发现的吲哚衍生的供体-受体环丙烷同时参与四个反应中心的能力通过其多米诺环二聚反应得以揭示（参见方案）。SnCl 4诱导的反应提供了具有pentaleno [1,6- a，b ]吲哚骨架的双吲哚产物。在此过程中，形成了两个新的环，三个CC键和四个立体中心，它们具有出色的化学，区域和立体选择性。

  DOI：10.1002/asia.202400272

  日期：——

  directing potential of weakly coordinating aldehyde group present at 3-position of indole was exploited for regioselective C2-H thioarylation over the possible C4-H functionalization. Mechanistic studies reveal that the process involves initial generation of thioaryl radical followed by sequential C−H activation, thiolate transfer, and reductive elimination.
