The method allows access to a) P-chiral biaryl phosphine oxides, b) atropo-enantioselective construction of sterically demanding biaryl backbones, and also c) selective assembly of axial and P-chiral compounds in excellent yields and diastereo- and enantioselectivities. Enantiospecific reductions provide monodentate chiral phosphorus(III) compounds having structures and biaryl backbones with proven importance as ligands in asymmetric catalysis.Chemistry, MultidisciplinaryChemistryasymmetric catalysisc-h activationchiral cp ligandsiridiump-chiralityasymmetric catalytic-reactionscyclopentadienyl ligandsatroposelective synthesiscarboxylic-acidsfunctionalizationactivationmonophosphinesatropisomersolefinationcyclizationtext::journal::journal article::research article
