commercially available [Ru(p-cymene)Cl2]2 and 1,4-bis(diphenylphosphino)butane catalyzes the racemization of aromatic α-hydroxy ketones very efficiently at room temperature. The racemization is fully compatible with a kinetic resolution catalyzed by a lipase from Pseudomonas stutzeri. This is the first example of dynamic kinetic resolution of α-hydroxy ketones at ambient temperature in which the metal and enzyme
由市售的[Ru(对-cymene)Cl 2 ] 2和1,4-双(二苯基膦基)丁烷形成的钌络合物在室温下非常有效地催化芳族α-羟基酮的外消旋化。外消旋化与由斯氏假单胞菌(Pseudomonas stutzeri)的脂肪酶催化的动力学拆分完全相容。这是环境温度下α-羟基酮动态动力学拆分的第一个例子,其中金属和酶催化剂在室温下在一个罐中协同工作,以定量产率获得具有很高对映选择性的α-羟基酮的酯。
