A series of chiral β-substituted alkane-phosphonates was synthesized in high enantioselectivities via the first rhodium-catalyzed asymmetric hydrogenation of the corresponding β-substituted-α,β-unsaturated phosphonates using a ferrocene-derived monophosphoramidite ligand, with which up to 99.5% ee have been achieved for the hydrogenation of (E)-substrates and 98.0% ee for (Z)-substrates.
