2,2′-Dimethoxy-1,1′-binaphthyl-3,3′-diboronic acid was prepared in 48% yield from 2,2′-dimethoxy-1,1′-binaphthyl and used as a key intermediate in Suzuki cross-coupling reactions to yield various 2,2′,3,3′-symmetrically substituted binaphthyl derivatives

3,3′-Biphenyl-2,2′-binaphthols (BINOLs) are precursors of phosphoric acids that are widely used as ligands and catalysts in organic reactions. In this report, two routes for the synthesis of (±)-3,3′-diphenyl BINOLs via (±)-3,3′ bis-halogenated BINOLs int

A variety of new chiral phosphoramidites was synthesised and tested in the copper-catalysed enantioselective conjugate addition of diethylzinc to cyclohexenone and chalcone in order to assess the structural features that are important for stereocontrol. A
Synthesis and application of macrocyclic binaphthyl ligands with extended chiral bias
Yan, Yuan-Yong,Widhalm, Michael
, p. 3607 - 3610 (2007/10/03)
Two macrocyclic and one non-cyclic chiral diphosphine ligand containing a 2,2'-bridged binaphthyl unit were synthesized in six steps from (R)-2,2'- dimethoxy-1,1'-binaphthyl in overall yields of 25 and 17%, respectively. The new ligands showed asymmetric inductions of up to 98% e.e. if used in palladium catalyzed allylic alkylation reactions.
