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
