A practical procedure has been developed for the dynamic kinetic resolution of 1,2-diarylethanols. This procedure employs a highly enantioselective lipase from Pseudomonas stutzeri (trade name, lipase TL) as the resolution catalyst and a ruthenium complex as the racemization catalyst. Sixteen 1,2-diarylethanols have been efficiently resolved to provide their acetyl derivatives with good yields (95-97%)
已经开发了一种用于1,2-二芳基乙醇的动态动力学拆分的实用程序。该方法使用来自斯氏假单胞菌(Pseudomonas stutzeri)的高度对映选择性脂肪酶(商品名,脂肪酶TL)作为拆分催化剂,并使用钌配合物作为消旋化催化剂。十六种1,2-二芳基乙醇已得到有效拆分,以使其乙酰基衍生物具有良好的收率(95-97%)和高的对映体过量率(96-99%)。
