An optically pure atropisomeric biphenylbisphosphine, Cy-BIMOP, has been prepared, and its rhodium(I) complex showed higher catalytic activity and better enantioselectivity with the reverse configuration than BIMOP, p-MeO-BIMOP, and BINAP in the asymmetric hydrogentions of (Z)-α-acetamidoxinnamic acid, itaconic acid, and its derivative.
