摘要
The desymmetrization of the prochiral tetrabromobiphenyl via asymmetric bromine-lithium exchange as a key step of synthesis of novel biphenyl-diphosphine ligands is reported. This new approach allows an easy access to twelve new enantiomerically pure atropisomeric ligands in one- to three-step reactions in good to excellent yields.
