method has been developed for the condensation of o‐aminoaryl ketones with α‐methylene ketones in the presence of catalytic amounts of LiBr to afford the corresponding fused cyclic quinolines in high yield using the Friedlander heteroannulation reaction. The reaction works at ambient temperature to give the products within 1.5–2 h.

AbstractThis study explores a green methodology for the synthesis of polysubstitutedquinolines through Friedländer annulation using water as a solvent. To evaluate the viability of this methodology, results obtained were compared with methods involving the usage of energy, such as mechanical stirring, heating, microwave irradiation, and solvent free heating reaction. To demonstrate the efficiency
摘要这项研究探索了一种绿色方法学,该方法通过使用水作为溶剂的弗里德兰德环化法合成多取代喹啉。为了评估该方法的可行性,将获得的结果与涉及能源使用的方法进行了比较,例如机械搅拌,加热,微波辐射和无溶剂加热反应。为了证明该方法的效率和一致性,已使用该方案进行了批量反应,并合成了许多喹啉衍生物,并通过1 H,13 C NMR,熔解范围和HR-MS对其进行了表征。 图形概要
