Precise chiral recognition was firstly realized in the construction of diastereomeric biaryl monophosphines by means of the substrate-directed asymmetric annulation reactions. A series of new chiral-bridged atropisomeric biphenyl monophosphine ligands with tunable dihedral angles was accordingly synthesized successfully without a resolution step being needed. Using these ligands, different kinds of axially chiral 1,1′-biaryl-2-phosphonates including the first reported quinolyl biaryl phosphonates were prepared in 42–97% yields with up to 96% ee via palladium-catalyzed asymmetric Suzuki coupling reactions.

A series of novel chiral-bridged atropisomeric monophosphine ligands were synthesized via convenient and simple pathways. The prepared ligands, especially for ligand 7d, were found to be highly effective in the Pd-catalyzed Suzuki-Miyaura coupling reactio
