Highly Enantioselective Hydrogenation of Amides via Dynamic Kinetic Resolution Under Low Pressure and Room Temperature

High-throughput screening and lab-scale optimization were combined to develop the catalytic system <i>trans</i>-RuCl<sub>2</sub>((<i>S</i>,<i>S</i>)-skewphos)((<i>R</i>,<i>R</i>)-dpen), 2-PrONa, and 2-PrOH. This system hydrogenates functionalized α-phenoxy and related amides at room temperature under 4 atm H<sub>2</sub> pressure to give chiral alcohols with up to 99% yield and in greater than 99% enantiomeric excess via dynamic kinetic resolution.
