An easy preparation of optically active 1,2-diol monotosylate derivatives by enzymatic hydrolysis is disclosed. Lipase PS ( BURKHOLDERIA CEPACIA) catalyzes the hydrolysis of racemic 2-acetoxyhexyl tosylate with excellent enantioselectivity to afford the corresponding optically active compounds. In this reaction, a unique temperature effect is observed. After optimizing the reaction conditions, this
公开了通过酶促水解容易制备光学活性的1,2-二醇单甲苯磺酸酯衍生物。脂肪酶 PS (BURKHOLDERIA CEPACIA) 以优异的对映选择性催化外消旋甲苯磺酸 2-乙酰氧基己酯的水解,以提供相应的旋光化合物。在该反应中,观察到独特的温度效应。优化反应条件后,该方法可广泛应用于各种高ee光学活性化合物的两种对映体的实际制备。
