therapeutically and also as visible‐light photoredox catalysts. In this work we report the application of an ultra-stable (US) Y zeolite as a promising green catalyst in the synthesis of a series of 1,4-dihydropyridines under microwave irradiation. Using the optimized reaction conditions, 21 compounds were prepared in 64-96% isolated yields. The recovery and recycle of the USY zeolite are also reported as well
摘要 Hantzsch 三组分反应是最著名的多组分反应,可提供已用于治疗的二氢
吡啶类化合物,也可用作可见光光氧化还原催化剂。在这项工作中,我们报告了超稳定 (US) Y
沸石作为一种有前途的绿色催化剂在微波辐射下合成一系列 1,4-
二氢吡啶中的应用。使用优化的反应条件,以 64-96% 的分离产率制备了 21 个化合物。还报告了 USY
沸石的回收和再循环及其完全表征。
