A highly efficient asymmetric hydrogenation of a series of γ-keto acid derivatives, including γ-keto acids, esters, and amides, using a Ni-(R,R)-QuinoxP* complex as the catalyst has been developed to afford chiral γ-hydroxy acid derivatives with excellent enantioselectivities, up to 99.9% ee. This method provides not only an economical one-pot approach for the synthesis of chiral γ-lactones but also
使用 Ni-( R , R )-QuinoxP* 配合物作为催化剂,开发了一系列 γ-酮酸衍生物(包括 γ-酮酸、酯和酰胺)的高效不对称氢化,以提供手性 γ-具有优异对映选择性的羟基酸衍生物,高达 99.9% ee。该方法不仅为合成手性 γ-内酯提供了一种经济的一锅法,而且还提供了 ( S )-去甲氟西汀(一种神经血清素再摄取抑制剂和药物合成的重要中间体)。
