Diacetato[(S)-(-)-5,5'-bis(diphenylphosphino)-4,4'-bi-1,3-benzodioxole]ruthenium(II) Usage And Synthesis

Reaction

Highly active highly enantioselective catalyst for hydrogenation of functionalized ketones. The acetate salts are frequently used for hydrogenation of allyl alcohols, unsaturated carboxylic acids and reductive amination.
Asymmetric hydrogenation of substituted allyl alcohols.

Uses

(S)-Ru(OAc)₂(SEGPHOS^?) can be used as a catalyst:

To prepare highly chemo, enantio, and diastereoselective primary β-amino lactams by asymmetric reductive amination of racemic β-keto lactams.
To synthesize chiral primary diarylmethylamines and sterically bulky benzylamines from diaryl and sterically hindered ketones via asymmetric reductive amination reaction.
For the conversion of levulinic acid to optically active γ-valerolactone via asymmetric hydrogenation reaction.
