  Initial structure–activity relationship of a novel class of nonpeptidyl GnRH receptor antagonists: 2-arylindoles

  摘要：

  A nonpeptidyl GnRH receptor antagonist (1), with a unique 2-arylindole core, was identified through the Merck inhouse screening for binding affinity on the rat GnRH receptor. SAR studies directed toward the alkoxy-ethanolamine and 2-aryl groups resulted in a simpler lead structure with improved activity. This compound 50 exhibits a 60-fold improvement in binding activity over our initial lead 1. (C) 2001 Elsevier Science Ltd. All rights reserved.

• Pd(II)-Catalyzed Intramolecular C(sp²)–H Arylation of Tryptamines Using the Nonsteric NH₂ as a Directing Group

  The free amine-directed C–H functionalization reactions are challenging and mainly restricted to bulky amines. In this work, we report the nonsteric NH2-directed Pd(II)-catalyzed intramolecular C(sp2)–H arylation of tryptamines, which enables the efficient, gram-scale, and regioselective synthesis of versatile 2-aryltryptamines (35 examples, up to 98% yield). This approach broadens the substrate scope

  游离胺指导的CH官能化反应具有挑战性，主要限于笨重的胺。在这项工作中，我们报告了非立体NH 2定向的Pd（II）催化的类固醇胺的分子内C（sp 2）–H芳基化反应，从而可以高效，克级和区域选择性地合成通用的2-芳基色胺（35个例子，最高可达98％）。这种方法拓宽了游离胺导向的C–H官能化的底物范围，而不仅限于笨重的胺底物。2-芳基色胺的后期精加工实现了复杂核心结构的多样化构建，这种结构在极有价值的天然产物（如金盏花石，鸟嘌呤和草碱）中普遍存在。

  An electrosynthesis of spiro-indolenines in batch and continuous flow was achieved through dearomative arylation of indoles with good functional group compatibility. User-friendly undivided cells were used under catalyst- and oxidant-free conditions. Moreover, the use of a flow electrolysis cell gave high daily productivity and excellent scale-up potential under less supporting electrolyte and higher
