MCM‐41‐SO3H, an ordered mesoporous silica material in which MCM‐41 with covalently anchored sulfonic acid groups was used as an acidic catalyst for the rapid and ‘green’ synthesis of pyrano[3,2‐c]pyridine derivatives under solvent‐free conditions. Reusability of the catalyst, high yields, short reaction times, simplicity and easy workup are advantages of this novel synthetic procedure compared to the
MC
M-41-SO 3 H,一种有序的介孔
二氧化硅材料,其中具有共价锚定
磺酸基团的MC
M-41被用作酸性催化剂,可在以下条件下快速并“绿色”合成
吡喃并[3,2-c]
吡啶衍生物无溶剂条件。与文献报道的常规方法相比,该新颖的合成方法的优点是催化剂的可重复使用性,高产率,短反应时间,简单和易于后处理。
