An improved synthesis of multifunctionalized pyrrolo[2,3,4-kl]acridine derivatives with different substituted patterns using silica sulfuric acid (SSA) as a heterogeneous catalyst under microwave irradiation conditions was developed. The reaction could be conducted by using readily available and inexpensive substrates within short periods of 12–15 min. under microwave irradiation. Compared with the
开发了使用二氧化硅硫酸 (SSA) 作为非均相催化剂在微波辐射条件下合成具有不同取代模式的多功能吡咯并 [2,3,4-kl] 吖啶衍生物的改进方法。该反应可以通过使用容易获得且价格低廉的底物在 12-15 分钟的短时间内在微波辐射下进行。与传统方法相比,该方法的显着优点是反应条件温和、操作简单、产率高、反应时间短、过程环保。
