Technical Notes:
1.Catalyst used for both hydrogenation and asymmetric transfer hydrogenation.
2.Ruthenium catalyst used as a key intermediate in a synthesis of a receptor agonist.
3.Convincing Catalytic Performance of Oxo-Tethered Ruthenium Complexes for Asymmetric Transfer Hydrogenation of Cyclic a-Halogenated Ketones through Dynamic Kinetic Resolution
