A sequence of f-phamidol-based tetradentate phosphine ligands have been developed and successfully used in iridium-catalyzed enantioselective hydrogenation of benzophenones to deliver chiral benzhydrols in almost quantitative yields and with excellent enantioselectivities (up to >99% yield and up to >99% ee). Moreover, the catalytic system shows a broad substrate scope and functional group tolerance
一系列基于f -phamidol 的四齿膦配体已开发出来,并成功用于铱催化的二苯甲酮对映选择性氢化,以几乎定量的产率和优异的对映选择性(高达 >99% 产率和高达 >99%)提供手性二苯甲醇ee)。此外,该催化系统显示出广泛的底物范围和官能团耐受性。该方法的合成实用性已通过克级实验和左西替利嗪的正式合成得到展示。
