Study on the Efficient Synthesis of Quinoline Derivatives from Cyclobutenones

在酸催化作用下,成功实现了3-氨基-2-环丁烯酮开环重排一步合成喹啉类化合物,对反应溶剂、催化剂、温度、投料比等影响因素进行了考察,在优化反应条件下催化合成了一系列喹啉类化合物,获得了较好的产率。该合成方法具有反应温度低、产率高以及反应迅速等优点,为喹啉类衍生物的合成建立了一种简单有效的新方法。

A series of quinoline derivatives were successfully obtained through opening-cyclization reaction of 3-amino-2-cyclobutanones in the presence of acid. By screening the reaction solvent, catalyst, temperature, feed ratio and other factors, the optimal reaction conditions were obtained. The method exhibits many advantages such as low temperature, high yield, rapid response and so on, and it establishes a simple and effective new method for the synthesis of quinoline derivatives.
