an effective strategy for the synthesis of porous polymers in recent years. Here, we report the synthesis of porous chiral phosphoric acids by this strategy. Moreover, these porous chiral phosphoric acids were found to enable highly enantioselective dearomatization reactions. Remarkably, after being reused for 10 runs, no obvious loss in catalytic activity and selectivity was observed. The features of
近年来,使用外部交联剂编织刚性芳烃结构单元已发展成为合成多孔聚合物的有效策略。在这里,我们报告了通过这种策略合成多孔手性磷酸。此外,发现这些多孔手性磷酸能够实现高度对映选择性的脱芳构化反应。值得注意的是,在重复使用 10 次后,没有观察到催化活性和选择性的明显损失。这些超交联多孔手性磷酸的高反应性、选择性、稳定性和可回收性等特点对实际催化剂设计具有重要意义。
