screening and lab-scale optimization were combined
to develop the catalytic system trans-RuCl2((S,S)-skewphos)((R,R)-dpen), 2-PrONa, and 2-PrOH. This system hydrogenates
functionalized α-phenoxy and related amides at room temperature
under 4 atm H2 pressure to give chiral alcohols with up
to 99% yield and in greater than 99% enantiomeric excess via dynamic
kinetic resolution.
