methacrylate polymers permits the synthesis of a soluble polymer for use in ruthenium(II)-catalyzed asymmetric transfer hydrogenation reactions. Using a 7:3 copolymer of a poly(ethylene glycol) ester and a hydroxyethyl ester, a derived ruthenium(II)/norephedrine complex catalyses reduction of acetophenone in up to 95% yield and 81% ee.
甲基丙烯酸酯聚合物的适当组合允许合成用于钌(II)催化的不对称转移氢化反应的可溶性聚合物。使用聚(乙二醇)酯和羟乙基酯的7:3共聚物,衍生的钌(II)/去甲麻黄碱络合物催化苯乙酮的还原,产率最高可达95%,ee可达81%。
