Application

Takasago Ligands and Complexes for Asymmetric Reactions
Catalytic ligand for:
  • Enantioselective synthesis of secondary allylic alcohols via enantioselective reductions of α,β-unsaturated ketones
  • Stereoselective preparation of cyclohexanone derivatives via rhodium-catalyzed rearrangement of allyl or allenic cyclobutanols
  • Cu-catalyzed asymmetric conjugate reduction of beta-substituted unsaturated phosphonates to give optically active beta-stereogenic alkylphosphonates
  • Asymmetric synthesis of cyclohexenones via Rh-catalyzed desymmetrization through enantioselective C-C bond activation and ring expansion of allenyl cyclobutanols
  • Enantioselective synthesis and crystal structure of P-stereogenic alkynylphosphine oxides by Rh-catalyzed [2+2+2] cycloaddition
