Hantzsch pyridine synthesis
The initial reaction product is a dihydropyridine which can be oxidized in a subsequent step to a pyridine. Aromatization Oxidation of 1,4-DHPs accounts for one of the easiest ways of accessing pyridine derivatives. wikipedia.org

如何判断一个基团是供电子还是吸电子基团？
哦不对，pyridine和pyrrole分别带的是EDG还是EWG？ 这种情况下，EDG和EWG一般具有以下结构特征： 可以再判断一下，苯甲醚苯环上连的是EDG还是EWG？苯甲腈呢？ 这里有个trick 建议画一下共振式，或许可以帮助理解。 最后附上总结参考： zhihu
