Herein, an efficient aerobic oxidative synthesis of pyrimidines was carried out using cinnamyl alcohols and amidines catalyzed by manganese oxide octahedral molecular sieve (OMS-2). The heterogeneous catalytic method features base-/additive-free conditions, wide substrate scope, use of O₂ as a green oxidant, and simple operation. Moreover, the OMS-2 catalyst prepared by the conventional reflux method demonstrates catalytic selectivity, activity, and excellent recyclability.

使用多相OMS-2催化剂从肉桂醇和am选择性合成嘧啶

在此，使用肉桂醇和由氧化锰八面体分子筛（OMS-2）催化的am进行了嘧啶的有效好氧氧化合成。该多相催化方法具有无碱/无添加剂的条件，较宽的底物范围，使用O ₂作为绿色氧化剂以及操作简单的特点。而且，通过常规回流方法制备的OMS-2催化剂表现出催化选择性，活性和优异的可循环性。
