New Chiral Diphosphine Ligands Designed to Have a Narrow Dihedral Angle in the Biaryl Backbone

A series of novel optically active diphosphine ligands, (4,4′-bi-1,3-benzodioxole)-5,5′-diylbis(diarylphosphine)s (6), which are called SEGPHOS, has been designed and synthesized with dihedral angles in the Ru complexes being less than that in the corresponding BINAP-Ru complex. The stereorecognition abilities of SEGPHOS-Ru complex catalysts in the asymmetric catalytic hydrogenation of a wide variety of carbonyl compounds are superior to those observed with BINAP-Ru complex catalysts.

Chiral diphosphine compound intermediate for preparing the same transition metal complex having the same diphosphine compound as ligand and asymmetric hydrogenation catalyst

A novel diphosphine compound of the formula (I): STR1 where R1 and R2 represent independently cycloalkyl, unsubstituted or substituted phenyl, or a five-membered heteroaromatic ring. The compound is useful as a ligand for an asymmetric reaction, in particular, as an asymmetric hydrogenation catalyst.
