Valuable vicinal 1,2‐diols can be prepared with high enantioselectivity by the asymmetric ruthenium‐catalyzed hydrogenation of aryl‐ and alkyl‐substituted α‐hydroxy ketones (see scheme). The ligands, which are distinguished by their modular construction, display excellent enantioface differentiation.
通过不对称钌催化的芳基和烷基取代的α-羟基酮的不对称氢化,可以制备高价的邻位1,2-二醇(参见方案)。配体以其模块化结构而著称,表现出出色的对映体分化。
