Beschreibung

Application

Takasago Ligands and Complexes for Asymmetric Reactions

(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.
