摘要:在 α 甲基苯乙烯与三聚醛反应生成 2,4,6-三甲基-4-苯基-1,3-二恶烷 (Vertacetal) 的 Prins 反应中,酸处理的蒙脱石用作催化剂.该反应的产物是一种生物活性化合物,可与 Gaba(γ-氨基丁酸)受体相互作用,具有芳香性.蒙脱石(用作该反应的催化剂)是通过用盐酸,硝酸,硫酸或氯乙酸处理制备的.考察了处理用酸及其他反应条件(反应温度,溶剂,化学反应物摩尔比,催化剂用量)对反应过程的影响.经酸处理的蒙脱石被证明是适合该反应的催化剂--在室温下使用不同的溶剂获得了高收率的所需产物 (>94%).溶剂的选择对反应至关重要--使用硝基甲烷或 1,4-二恶烷可获得最佳结果.催化剂经300oc煅烧后可重复使用1次.
