method for regioselective synthesis of C1-functionalised 3-arylbenzo[f]quinoline has been demonstrated via γ-selective aromatization using β-ketoester, 2-naphthylamine and aromatic aldehyde by employing 10 mol% camphorsulfonic acid as the catalyst in acetonitrile at 70 °C. In this approach, two C–C bond formations will result in functionalised benzo[f]quinoline in a one-pot three-component reaction
通过在70°C的乙腈中使用10 mol%樟脑磺酸作为催化剂,使用β-酮酸酯,2-萘胺和芳香醛进行γ-选择性芳构化,已证明了C1官能化的3-芳基苯并[ f ]喹啉区域选择性合成的有效方法。℃。在这种方法中,两个碳原子-碳键的形成将导致一锅三组分反应中的官能化苯并[ f ]喹啉。另外,本方案具有多样化的底物范围,具有良好的产率。此外,该协议直接用于合成2-(3-(萘-2-基)苯并[ f ]喹啉-1-基)乙酸烷基酯,2-(3-(杂芳族)苯并[ f ]烯丙基]喹啉-1-基)乙酸酯和官能化的1,2,3-三取代的苯并[ f ]喹啉。
