immobilization on a highly cross-linked three-dimensional network structure through covalent interactions. The microgel-supported organocatalyst has been successfully applied to catalyze the asymmetric alcoholysis reaction in high yields and good stereoselectivity (up to 90% ee). Furthermore, the polymeric catalysts could be recovered easily and reused multiple times (5 runs) without apparent loss of
通过共价相互作用固定在高度交联的三维网络结构上,合成了一种新型的热敏双功能磺酰胺微凝胶催化剂。微凝胶负载的有机催化剂已成功应用于催化不对称醇解反应,产率高,立体选择性好(高达 90% ee)。此外,聚合物催化剂可以很容易地回收并重复使用多次(5次运行),而不会明显损失催化活性和对映选择性。
