The enantioselective hydrogenation of 1,3-diarylpropane-1,3-diones with chiral Ru(II)-diphosphine catalyst has been studied. In a first approach it was found, that Tol-BINAP together with Ru(COD)methallyl 2 formed the most selective catalyst. One of the C 2 -symmetric enantiopure 1,3-diols obtained

The attainment of both high catalytic efficiency and high enantioselectivity remains a formidable challenge in asymmetric catalysis. [1] Bidentate ligands composed of trans-2,5disubstituted phospholane groups have been shown to be useful in asymmetric catalytic hydrogenation reactions. Despite high
