Application

Takasago Ligands and Complexes for Asymmetric Reactions
Chiral biaryl bisphosphine catalytic ligand used for:
  • Rhodium-catalyzed asymmetric formal olefination or cycloaddition of 1,3-dicarbonyl compounds with 1,6-diynes or 1,6-enynes
  • Stereoselective preparation of homoallylic alcohols via Ir-catalyzed stereoselective transfer hydrogenative crotylation of an allylic acetate with alcohols or aldehydes
  • Regio- and stereoselective preparation of axially chiral arylnaphthalene derivatives via rhodium-catalyzed [2+2+2] cycloaddition of diynes with naphthalenepropynoic acid derivatives
  • Diastereo- and enantioselective hydrogenation of α-amino-β-keto ester hydrochlorides catalyzed by an iridium complex
  • Preparation of dihydroisoquinolinones via nickel-catalyzed denitrogenative annulation of benzotriazinones with 1,3-dienes and alkenes
  • Stereoselective preparation of indanol derivatives via Rh-catalyzed enantioselective alkynylative cyclization of allenyl aldehydes with terminal alkynes
