Hybrid phosphorus ligands enable a Rh-catalyzed enantioselective anti-Markovnikov hydroformylation of unfunctionalized 1,1-disubstituted alkenes to provide linear aldehydes with β-chirality in high yields and enantioselectivities under mild conditions. In a large-scale synthesis, a very low catalyst loading (0.05 mol %) furnished the desired product in good yield and undiminished selectivity.
