A series of new highly substituted isoquinoline derivatives was obtained from the reaction of 2‐(1‐substituted piperidin‐4‐ylidene)malononitrile, benzaldehyde and malononitrile or cyanoacetate in ionic liquid at 50°C. This novel procedure was different from the previous method in the synthesis of isoquinoline using pyridine fragment as reactant to construct benzene ring, and as well as had the advantages
在50°C的温度下,2-(1-取代的哌啶-4-亚甲基)丙二腈,苯甲醛和丙二腈或氰基乙酸酯的反应获得了一系列新的高度取代的异喹啉衍生物。该新方法与以前的方法不同,在于使用吡啶片段作为反应物构建苯环来合成异喹啉,并且具有一锅法,温和且对环境无害的优点。根据进一步的实验结果,提出了一种可能的机理。J.杂环化学,(2009)。
