A new and highly efficient enzymatic aminolysis approach for kinetic resolution of aromatic α-hydroxy acid in non-aqueous media has been developed. The corresponding α-hydroxyl acid ester was employed as the substrate, and commercially available Candida antarctica lipase B is used as the biocatalyst, anhydrous ammonia is the resolving agent. Reactions can be proceeded smoothly in organic solvent at
已开发出一种新的高效酶解氨基方法,用于在非水介质中动力学拆分芳香族α-羟基酸。相应的α-羟基酸酯用作底物,市售的南极假丝酵母脂肪酶B用作生物催化剂,无水氨为拆分剂。反应可以在环境温度下在有机溶剂中顺利进行。由于使用了有机介质,因此允许高浓度的底物,获得的产品收率高达49%,ee值高达99%,E值> 300,代表了大批量生产的诱人且有希望的方案规模的准备工作。
