The solid-phase synthesis of new asymmetric transfer hydrogenation catalysts as well as the use of these silica supported systems in batch and flow reactors is reported. The ruthenium complex of NH-benzyl-(1R,2S)-(À)-norephedrine covalently tethered to silica showed a high activity and enantioselect
## Abstract The chiral amino amide **3** was derived from L‐proline and used for the [RuCl~2~(__p__‐cymene)]~2~‐catalyzed asymmetric transfer hydrogenation of prochiral ketones performed in water. Moderate to good chemical selectivities (up to 95% yield) and enantioselectivities (up to 90% ee) were
