An efficient Ru catalyst constructed from simple and commercially available triphenylphosphane and enantiopure (1S,1′S)‐1,1′‐biisoindoline (BIDN) was applied to the asymmetric hydrogenation of aromatic ketones. A range of simple aromatic ketones could be hydrogenated with good to excellent enantioselectivities (up to 95 % ee). An appropriate enantioselective transition state was proposed to explain
由简单的市售三苯膦和对映纯(1 S,1 'S)-1,1'-二异吲哚啉(BIDN)构成的高效Ru催化剂用于芳族酮的不对称加氢。可以将一系列简单的芳族酮氢化,具有良好至优异的对映选择性(最高95%ee)。提出了合适的对映选择性过渡态来解释该催化体系获得的高对映选择性。这项研究代表了第一个建立具有简单非手性单膦烷用于高对映选择性氢化的Noyori型催化剂的实例。
