✦ Synopsis

We developed an efficient, easily available, and easy to use proline amide-based ruthenium(II) catalysts for the asymmetric hydride transfer reduction of prochiral ketones and e.e.s up to 98.8% have been measured.

## 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
