Synthesis of Axially Chiral 2,2′-Bisphosphobiarenes via a Nickel-Catalyzed Asymmetric Ullmann Coupling: General Access to Privileged Chiral Ligands without Optical Resolution

We report an asymmetric homocoupling of ortho-(iodo)arylphosphine oxides and ortho-(iodo)arylphosphonates resulting in highly enantioenriched axially chiral bisphosphine oxides and bisphosphonates. These products are readily converted to enantioenriched b

Diastereospecific intramolecular Ullmann couplings: Unique chiral auxiliary for the preparation of 3,3′-disubstituted MeO-BIPHEP derivatives

A chiral auxiliary is described that provides only one diastereomer during Intramolecular Ullmann couplings. Treatment of five Ullmann coupling precursors with Cu powder in DMF at 115 °C provides 2,2′,3,3′,6,6′- hexasubstituted 1,1′-biphenyls as single di

ISOMERISATION OF CHIRAL HOMOGENEOUS O,O'-DIHYDROXYBIPHENYL DERIVATIVES

Chiral homogeneous o,o'-dihydroxybiphenyl derivatives, which either act as bisphosphine ligands of enantioselective transition metal complex catalysts, or are used as intermediate products for producing ligands of this type, can be isomerised by thermal treatment, optionally in the presence of substances with an alkaline action, to produce a mixture of both enantiomers. The inventive method permits the targeted production of a ligand for enantioselective transition metal complex catalysts in (R)- or (S)- form, enabling the undesired enantiomer to be used.
