Ru-catalyzed asymmetric transfer hydrogenation of acyl phosphonates: reduction proceeded from the opposite face relative to that observed in the analogous reduction of α-keto esters. The first highly selective catalytic hydrogenation of acyl phosphonates was utilized in the dynamic kinetic resolution of α-aryl acyl phosphonates, providing β-stereogenic α-hydroxy phosphonic acid derivatives.
在 Ru 催化的酰基膦酸酯的不对称转移氢化中观察到了意想不到的二分法:相对于在 α-酮酯的类似还原中观察到的相反面进行还原。酰基膦酸酯的第一次高选择性催化氢化用于 α-芳基酰基膦酸酯的动态动力学拆分,提供 β-立体异构 α-羟基膦酸衍生物。
