A straightforward synthesis of substituted pyrroles using zirconium chloride-catalyzed modified Paal-Knorr method has been accomplished under ultrasound irradiation. Compared to known methods, this new method provides as easy access to various substituted pyrroles in good to excellent yields with short reaction times.
在超声辐射下，利用氯化锆催化的改良帕尔-克诺尔方法实现了取代吡咯的直接合成。与已知方法相比，这种新方法能够在短反应时间内以良好至优异的产率轻松获得各种取代吡咯。
