The Ru-catalyzed asymmetric hydrogenation of ketones with chiral diamine and monodentate achiral phosphine has been developed. A wide range of ketones were hydrogenated to afford the corresponding chiral secondary alcohols in good to excellent enantioselectivities (up to 98.1% ee). In addition, an appropriate mechanism for the asymmetric hydrogenation was proposed and verified by NMR spectroscopy.
已经开发了Ru手性二胺和单齿非手性膦对Ru催化的酮的不对称加氢反应。将多种酮氢化,得到相应的手性仲醇,对映体选择性好至极好(高达98.1%ee)。此外,提出了合适的不对称氢化机理,并通过NMR光谱进行了验证。
