(S)-Selective kinetic resolution was achieved through the use of a commercially available protease, which was activated with a combination of two different surfactants. The kinetic resolution (KR) process was optimized with respect to activation of the protease and to the acyl donor. The KR proved to be compatible with a range of functionalized sec-alcohols, giving good to high enantiomeric ratio values
通过使用可商购的蛋白酶实现(S)-选择性动力学拆分,该蛋白酶被两种不同表面活性剂的组合激活。关于蛋白酶和酰基供体的活化,优化了动力学拆分(KR)过程。事实证明,KR与多种官能化仲醇兼容,对映体比率值高至高(高达> 200)。将酶促拆分与钌催化的消旋作用结合使用,可得到仲醇的(S)选择性动态动力学拆分(DKR)。DKR工艺在非常温和的反应条件下工作,以高收率和出色的对映选择性提供相应的酯。
