  Synthesis of substituted quinolines via the condensation of anilines with aliphatic and aromatic aldehydes in the presence of transition metal and rare-earth metal catalysts

  摘要：

  Novel catalyst complexes derived from transition metal and rare-earth metal compounds have been developed for the condensation of anilines with aliphatic and aromatic aldehydes to give the corresponding 2,3-disubstituted quinolines in high yields.

  We report the reaction behaviour of arylamines with nitroalkenes in the presence of bismuth(iii) triflate (10 mol%) and diacetoxyiodobenzene (10 mol%). We obtained 2,3-dialkylquinoline derivatives instead of the expected 3-alkylindole derivatives. The present reaction is an alternative approach for the synthesis of 2,3-dialkylquinoline derivatives under milder conditions. Furthermore, we establish

  我们报告了在三氟甲磺酸铋（iii）（10 mol％）和二乙酰氧基碘苯（10 mol％）存在下芳基胺与硝基烯烃的反应行为。我们获得了2,3-二烷基喹啉衍生物，而不是预期的3-烷基吲哚衍生物。本反应是在较温和的条件下合成2，3-二烷基喹啉衍生物的另一种方法。此外，我们使用高斯09软件[B3LYP / 6-311 + G（d，p）]通过理论计算建立了机理途径，表明传统的氮杂-迈克尔反应比迈克尔加成反应更可取。脂肪族硝基烯烃的行为与芳香族硝基烯烃不同。氮杂-迈克尔加合物通过消除水而生成亚胺，水可能互变为相应的烯胺。所得的亚胺和烯胺中间体一起反应，得到所需的喹啉衍生物。该方案的优点是连续形成一个CN和两个CC键，区域选择性高，底物范围宽和产率高。

  A variety of aminoarenes react with aliphatic aldehydes in the presence of a catalytic amount of a rhodium complex and an excess amount of the corresponding nitroarenes at 180 °C to give 2-alkyl- and 2,3-dialkyl-substituted quinolines in excellent yields. Among the rhodium complexes examined, [Rh(norbornadiene)Cl]2 exhibits the highest activity as a catalyst. Thus, 2-methyl-, 2-ethyl-3-methyl-, 2-propyl-3-ethyl-

  在催化量的铑配合物和过量相应硝基芳烃的存在下，多种氨基芳烃在 180 °C 下与脂肪醛反应，以极好的收率得到 2-烷基和 2,3-二烷基取代的喹啉。在所检测的铑配合物中，[Rh(降冰片二烯)Cl]2 作为催化剂表现出最高的活性。因此，2-甲基-、2-乙基-3-甲基-、2-丙基-3-乙基-和2-丁基-3-丙基喹啉衍生物很容易从氨基芳烃和乙醛、丙醛、丁醛和戊醛中获得分别。
• Ruthenium-catalyzed reductive cyclization of nitroarenes with trialkylamines leading to quinolines

  Nitroarenes react with trialkylamines in the presence of a catalytic amount of a ruthenium catalyst together with tin(II) chloride dihydrate at 180 °C in an aqueous medium (toluene–H2O) to afford the corresponding quinolines in moderate to good yields. The catalytic pathway seems to be proceeded via a sequence involving initial reduction of nitroarenes to anilines, alkyl group transfer from alkylamines

  硝基芳烃与三烷基胺在催化量的钌催化剂与二水合氯化锡（II）二水合物的存在下，在水介质（甲苯-H 2 O）中于180°C反应，以中等至良好的收率得到相应的喹啉。催化途径似乎是通过以下顺序进行的：首先将硝基芳烃还原为苯胺，烷基从烷基胺转移至苯胺以形成亚胺，亚胺二聚和杂环化。
