Abstract
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.
