Xu, Guangqing; Li, Minghong; Wang, Shouliang; Tang, Wenjun published the artcile< Efficient synthesis of P-chiral biaryl phosphonates by stereoselective intramolecular cyclization>, Quality Control of 135999-16-5, the main research area is chiral biaryl phosphonate stereoselective preparation; palladium catalyzed intramol asym cyclization diaryl bromo arylphosphonate; crystal mol structure biaryl phosphonate.
A series of P-chiral biaryl phosphonates were efficiently synthesized from diaryl 2-bromo arylphosphonates in high yields (up to 92%) and good enantioselectivities (up to 88% ee) through a palladium-catalyzed asym. cyclization with a novel P-chiral biaryl monophosphorus ligand. The P-chiral biaryl phosphonate can be rapidly transformed to both antipodes of a P-chiral dialkyl biaryl monophosphorus structure. The method provides a convenient access to various P-chiral biaryl monophosphines.
