以4(R)-羟基脯氨酸为原料,合成了高分子负载的脯氨酸衍生物,并用来催化丙酮对邻-和对-硝基苯甲醛的直接不对称Aldol加成反应,ee值最高可达80%,催化剂至少可以重复利用三次.
With 4 (R) -hydroxyproline as the raw material, a polymer-supported proline derivative was synthesized and used to catalyze the direct asymmetric Aldol addition reaction of o- and p-nitrobenzaldehydes by acetone. The ee value Up to 80%, the catalyst can be reused at least three times.
