This catalyst is composed of strong base and ruthenium complex constituted of diphosphine and diamine ligand and has high carbonyl and enantio selectivity in asymmetric hydrogenation of ketones. Chiral alcohol having high optical activity can be synthesized by means of this catalyst under mild condition from normal to ten atmospheric pressure.

These Ru(II) complexes having optical diamine or arene ligands are more beneficial catalysts for producing chiral alcohols and amines from asymmetric reduction of C=O and C=N bonds. 2-propanol and formic acid are well-behaving reduction agents. Asymmetric reduction using these hydrogenation donors and hydrogenation catarysts is not deeded special facilities or machines.

These are chiral compounds synthesized by Noyori catalysts and various hydrogenation catalysts.
