straightforward, fast, inexpensive, and environmentally friendly synthesis of 1,2,3,4,5-pentasubstituted derivatives of pyrrole, which were produced in one-pot reactions of 3-oxoanilides with hydrazides of carboxylic acids, catalyzed by 10 mol % VOSO4·H2O. The reactions were carried out in ethanol in contact with air as the oxidant. The 19 pyrroles obtained were usually crystalline and did not require purification
我们介绍了吡咯的1,2,3,4,5-五取代衍生物的直接,快速,廉价和环保的合成方法,该合成方法是在3-氧苯胺与羧酸酰肼的一锅反应中,由10催化摩尔%VOSO 4 ·H 2 O的反应在乙醇中与空气接触作为氧化剂进行。所获得的19种吡咯通常是结晶的,不需要纯化。该反应容许两种底物中的各种取代基。所有产品均具有红外,核磁共振,紫外可见光谱和元素分析的特征。通过X射线单晶分析明确确定了产物和中间体的分子结构。
