Application

(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.
