The asymmetric transfer hydrogenation (ATH) of α-keto-1,4-diamides using a tethered Ru/TsDPEN catalyst was achieved in high ee. Studies on derivatives identified the structural elements which lead to the highest enantioselectivities in the products. The α-keto-amide reduction products have been converted to a range of synthetically valuable derivatives.
使用系留的 Ru/TsDPEN 催化剂在高 ee 下实现了 α-酮基-1,4-二酰胺的不对称转移氢化(ATH)。对衍生物的研究确定了导致产品中最高对映选择性的结构元素。α-酮酰胺还原产物已转化为一系列具有合成价值的衍生物。
