General description

The product is a diphenylphosphinobenzoic acid (DPPBA) based ligand for the palladium-catalyzed asymmetric allylic alkylation with a high degree of enantioselectivity.

Application

Takasago Ligands and Complexes for Asymmetric Reactions
Catalytic ligand used for:
  • Enantioselective synthesis of dihydrobenzofurans and dihydronaphthofurans via olefin isomerization/enantioselective intramolecular Alder-ene reaction of enynes catalyzed by Rh
  • Preparation of axially chiral biaryl compounds by gold-catalyzed stereoselective intramolecular hydroarylation
  • Preparation of chiral 3-alkyl-substituted indolines by tandem condensation-asymmetric hydrogenation of indoles with aldehydes, catalyzed by Bronsted acids and palladium BINAP complexes
  • Stereoselective preparation of hydrindanes and decalins containing up to four contiguous stereocenters via rhodium-catalyzed [2+2+2] cycloaddition of ene-allenes with allenes
  • Rhodium-catalyzed asymmetric formal olefination or cycloaddition of 1,3-dicarbonyl compounds with 1,6-diynes or 1,6-enynes
  • Stereoselective preparation of 2,3-substituted indolines via Pd-catalyzed hydrogenation of (α-hydroxyalkyl)indoles
