A set of ten tricyclic pyrrole-2-carboxamides was synthesized by a Paal-Knorr cyclization under rapid and mild conditions using microwave irradiation. All compounds were also prepared using conventional heating techniques. An efficiency comparison of time, yield and effort clearly proved the microwave technique to be superior.
在快速温和的条件下,利用微波辐照,通过帕尔-克诺尔环化法合成了一组十个三环吡咯-2-甲酰胺。所有化合物也都是用传统加热技术制备的。对时间、产量和工作量进行的效率比较清楚地证明了微波技术的优越性。
