Description
(S)-3,3'-Bis([1,1':3',1''-terphenyl]-5'-yl)-[1,1'-binaphthalene]-2,2'-diol features a chiral binaphthyl scaffold with sterically demanding terphenyl substituents that enhance rigidity and define a deep, well-shielded chiral pocket. This configuration promotes high enantioselectivity in asymmetric catalysis and stabilizes transition states through π–π interactions. The diol functionality enables metal coordination and hydrogen bonding networks, making it effective in asymmetric synthesis and ligand design.
Application
(S)-3,3'-Bis([1,1':3',1''-terphenyl]-5'-yl)-[1,1'-binaphthalene]-2,2'-diol serves as a sterically hindered, enantiomerically pure chiral ligand that facilitates asymmetric catalysis in transition-metal-catalyzed reactions. Its rigid binaphthyl backbone and extended terphenyl substituents provide enhanced stereocontrol and robustness under varied reaction conditions, enabling high enantioselectivity in cross-coupling and hydrogenation processes. The diol functionality offers reliable coordination to metal centers while maintaining bench stability and ease of purification.
