A new atropisomeric biphenylbisphosphine, MOC-BIMOP, has been prepared in enantiomerically pure form and its rhodium(I) complex proved to be an efficient catalyst in the asymmetric hydrogenations of alpha-aminoketone hydrochloride and itaconic acid. A possible mechanism of our origin has been described for the hydrogenations.
