• 2-Substituted-2,3-dihydro-1H-quinolin-4-ones via Acid-Catalyzed Tandem Rupe Rearrangement-Donnelly-Farrell Ring Closure of 2-(3′-Hydroxy­propynyl)anilines
  作者：Federica Pisaneschi、Alan Spivey、Jimmy Sejberg、Cecile Blain、Wang Ng、Eric Aboagye

  日期：2011.1

  A range of 2-substituted 2,3-dihydro-1H-quinolin-4-ones have been synthesized from anilines by a two-step process involving Sonogashira coupling with a propargyl alcohol then acid-catalyzed cyclization of the resulting 2-(3′-hydroxypropynyl)anilines. The cyclization reaction appears to proceed via re­gioselective rearrangement of the propargyl alcohol to an α,β-unsaturated ketone (Rupe rearrangement) and then 6-endo-trig ring closure (Donnelly-Farrell cyclization). The isolation of the α,β-­unsaturated ketone intermediate in one example supports this pathway.

  一系列2-取代的2,3-二氢-1H-喹啉-4-酮是通过两步反应从苯胺合成的，首先是与丙炔醇进行Sonogashira偶联，然后是对得到的2-(3′-羟基丙炔基)苯胺进行酸催化环化。环化反应似乎通过丙炔醇的区域选择性重排形成α,β-不饱和酮（Rupe重排），然后是6-端环关闭（Donnelly-Farrell环化）。在一个例子中，α,β-不饱和酮中间体的分离支持了该路径。

  Herein, we present our results on the development of a waste-minimized protocol for the synthesis of oxindoles using cyclopentyl methyl ether (CPME) as a safe and green reaction medium and palladium on carbon (Pd/C) as a reusable catalyst. This protocol is efficiently applied to a variety of substrates affording products with excellent yields, minimal metal contamination and minimum waste production

  在此，我们展示了我们开发一种废物最小化方案的结果，该方案使用环戊基甲基醚 (CPME) 作为安全和绿色的反应介质，钯碳 (Pd/C) 作为可重复使用的催化剂来合成羟吲哚。该协议有效地应用于各种基材，提供具有出色产量、最小金属污染和最小废物产生的产品。催化剂被回收并重复使用连续四次，没有任何明显的效率损失。此外，产品通过简单的庚烷沉淀分离，无需色谱分离，CPME和庚烷均被回收。为所提出的协议计算的低 E 因子反映了废物最小化。
