Enantioselective Rh-Catalyzed Hydrogenation of N-Acyl Dehydroamino Esters and Enamides with Monodentate Phosphoramidite Ligands
2009
Chiral 单音的有牙齿的 phosphoramidite ligands 方便地在好收益从 1,1 ′-bi-2-naphthol (BINOL ) 和(S)-pyrrolidine 被准备,它是在 enantioselective 的有效 chiral ligands dehydroamino 酉旨并且在在低加氢压力的酰胺的催化金老的加氢。高变换率(多达 99% 为 dehydroamino 酉旨并且在酰胺) 并且好 enantioselectivity (为 dehydroamino 酉旨的多达 96.3% ee 和 91.7% ee 为在酰胺) 被获得。
