Description
(R)-SYNPHOS is a chiral bisphosphine ligand featuring a rigid, electron-rich backbone that enables high enantioselectivity in palladium-catalyzed cross-coupling reactions. This bench-stable, moisture-tolerant ligand integrates seamlessly into asymmetric synthesis workflows, delivering consistent stereocontrol in C–C and C–heteroatom bond formation.
Application
(R)-SYNPHOS is a chiral bisphosphine ligand that enables highly enantioselective transition-metal-catalyzed reactions, particularly in palladium- and nickel-mediated cross-couplings. Its robust stereochemical integrity and broad functional group tolerance facilitate efficient synthesis of complex chiral molecules. The ligand demonstrates excellent performance in Suzuki-Miyaura and Negishi couplings, offering consistent high enantiomeric excesses and reliable bench stability.
