  通过（生物）可用醇和氨基芳烃的交叉脱氢偶联，温和高效地合成取代的喹啉

  摘要：

  AbstractA ruthenium‐catalysed dehydrogenative cross‐coupling of primary alcohols and imines in the presence of TFA provided a library of differently substituted quinolines. Imines can be prepared in situ from various anilines and several benzyl alcohols using a ruthenium‐catalysed hydrogen‐transfer procedure. Without changing the catalyst, quinolines can be obtained in moderate to good yields by adding various primary alcohols in the presence of TFA (30 mol%) via a “telescopic” protocol. The use of alcohols, the absence of strong oxidants and the diversity of potential starting materials make this modern version of the Skraup reaction superior to most of the conventional quinoline syntheses.magnified image

• Zinc cation supported on carrageenan magnetic nanoparticles: A novel, green and efficient catalytic system for one-pot three-component synthesis of quinoline derivatives
  作者：Fariba Keshavarzipour、Hossein Tavakol

  日期：2017.8

  This is the first report of supporting zinc cation on ƛ‐carrageenan/Fe3O4 magnetic nanoparticles. The structural and magnetic properties of this hybrid (Zn2+/ƛ‐carrageenan/Fe3O4 nanoparticles) were identified using various techniques. This green and efficient catalytic system was applied in the synthesis of biologically important quinolines. The products were obtained in good to high yields (52–95%)

  这是第一个在ƛ-卡拉胶/ Fe 3 O 4磁性纳米粒子上支持锌阳离子的报告。使用各种技术鉴定了这种杂化物（Zn 2 + /β-卡拉胶/ Fe 3 O 4纳米颗粒）的结构和磁性。这种绿色高效的催化体系被用于合成生物学上重要的喹啉。从一锅法反应过程中获得的产品，收率高至高（52-95％），涉及芳族醛，可烯醇化醛和苯胺衍生物。我们的方法具有许多优点，例如反应条件温和，易于后处理，使用可重复使用的磁性催化剂和高收率的产品。
• One-pot synthesis of quinoline derivatives using choline chloride/tin (II) chloride deep eutectic solvent as a green catalyst
  作者：Dana Shahabi、Hossein Tavakol

  日期：2016.8

  In this work, various quinoline derivatives were prepared efficiently through a one-pot, three component synthesis using choline chloride/tin(II) chloride (ChCl·2SnCl2) deep eutectic solvent (DES) as a green catalyst. The procedure is free of using toxic solvents or catalyst and it could be categorized as a green method. In this procedure, aniline derivatives, aromatic aldehydes and enolizable aldehydes

  在这项工作中，使用氯化胆碱/氯化锡（II）（ChCl·2SnCl2）深共熔溶剂（DES）作为绿色催化剂，通过一锅，三组分合成有效地制备了各种喹啉衍生物。该程序无需使用有毒溶剂或催化剂，可以归类为绿色方法。在此过程中，在同时存在溶剂和反应催化剂的DES存在下，将苯胺衍生物，芳族醛和可烯醇化的醛混合。使用这种方法，喹啉衍生物仅在60°C的2-3小时内即可合成，产率高（54-97％）。通过色谱法纯化所有产物，并在乙醇中重结晶。所使用的DES已被回收了4次，而其活性并未受到重大损失。
• Practical and Simple Synthesis of Substituted Quinolines by an HCl−DMSO System on a Large Scale:  Remarkable Effect of the Chloride Ion
  作者：Shin-ya Tanaka、Makoto Yasuda、Akio Baba

  DOI：10.1021/jo052004y

  日期：2006.1.1

  A variety of substituted quinolines are synthesized from imines and enolizable carbonyl compounds under aerobic conditions, in which only water is a byproduct. In DMSO, a catalytic amount of HCl activates carbonyl compounds quite effectively to give the quinolines. A simple and practical procedure is demonstrated on a large scale.
