Synthesis of Atropisomeric 2,2'-Bis(dicyclohexylphosphino)-6,6'-dimethyl-1,1'-biphenyl (BICHEP) and Its Use in Rh(I)-catalyzed Asymmetric Hydrogenation of Prochiral Olefins

The atropisomeric bis(dialkylarylphosphine) ligands, (R)-(-)- and (S)-(+)-2,2'-bis(dicyclohexylphosphino)-6,6'-dimethyl-1,1'-biphenyl (BICHEP) (1) have been newly synthesized, whose Rh(I) complexes are highly efficient catalysts for asymmetric hydrogenations of ethyl α-(benzamido)cinnamate and dimethyl itaconate in up to 98percent yields and 98-99percent enantiomeric excess.
