accessible tridentate ferrocene-based diamine-phosphine sulfonamide (f-diaphos) ligands were successfully developed for iridium-catalyzed asymmetric hydrogenation of ketones. The f-diaphos ligands exhibited excellent enantioselectivity and superb reactivity in Ir-catalyzed asymmetric hydrogenation of ketones (for arylalkyl ketones, (S)-selectivity, up to 99.4% ee, and 100 000 TON; for diaryl ketones, (R)-selectivity
成功开发出了一系列基于空气的,易于接触的三齿二茂铁基二胺-膦磺酰胺(f-diaphos)配体,用于铱催化的酮的不对称氢化。f-重氮磷配体在Ir催化的酮的不对称加氢反应中表现出出色的对映选择性和极好的反应性(对于芳烷基酮,(S)选择性高达99.4%ee和100000 TON;对于二芳基酮,(R)选择性,高达ee的98.2%和10000吨)。该协议可以很容易地在克规模上进行,从而为各种药物提供了机会。
