efficient and green procedure has been developed for the synthesis of 1,8-dioxo-octahydroxanthenes derivatives. The reaction was carried out in water under ultrasound irradiation, using nanosized MCM-41-SO(3)H. In this method, several types of aromatic aldehyde, containing electron-withdrawing groups as well as electron-donating groups, were rapidly converted to the corresponding 1,8-dioxo-octahydroxanthenes
已经开发出一种有效且绿色的方法来合成1,8-二氧代-八氢氧杂蒽衍生物。反应是使用纳米级MCM-41-SO(3)H在超声辐射下于水中进行的。在这种方法中,含有吸电子基团和供电子基团的几种类型的芳族醛以良好的收率迅速转化为相应的1,8-二氧-八氧杂蒽。这种新颖的合成方法尤其受青睐,因为它提供了纳米级MCM-41-SO(3)H和超声辐射的协同作用,与传统方法报道的常规方法相比,该方法具有高收率,反应时间短,简单且易于后处理的优点。文献。
