ordered mesoporous silica material MCM-41 with covalently anchored sulfonic acid groups located inside the mesochannels, was used as an acid catalyst for the rapid and ‘green’ synthesis of 2,3-dihydroquinazolin-4(1H)-one derivatives under solvent-free condition. This novel synthetic method offers several advantages, such as excellent yields, simple procedure, short reaction times, and mild reaction
MCM-41-SO 3 H(有序介孔二氧化硅材料MCM-41,其介孔内具有共价锚定的磺酸基团)被用作酸催化剂,用于快速和“绿色”合成2,3-二氢喹唑啉-4(1在无溶剂条件下为H)一衍生物。这种新颖的合成方法具有许多优点,例如产率高,操作简单,反应时间短和反应条件温和。 MCM-41-SO 3 H-纳米催化剂-2,3-二氢喹唑啉酮-多组分反应-无溶剂条件
