was synthesized with 27% overall yield over six steps from 2-bromo-1-methyl-4-nitrobenzene as starting material. Its derivatization was achieved via Friedel–Crafts reaction catalyzed by anhydrous stannic chloride with various acyl chlorides giving 3-acyl-1-phenylpyrroles as the main products.
摘要从2-溴-1-经六步合成了一种新型的吡咯并苯并恶唑硼酸酯6-(吡咯-1-基)-1,3-二氢-1-羟基-2,1-苯并恶硼酸酯,其总收率为27%。以甲基-4-硝基苯为原料。它的衍生化是通过无水锡氯化物与各种酰基氯催化的Friedel-Crafts反应实现的,从而以3-酰基-1-苯基吡咯为主要产物。
