Highly enantioselective hydrogenation of (Z)-N-sulfonyl-α-dehydroamido boronic esters using a JosiPhos-type ligand is realized for the first time. This method enables the convenient synthesis of a series of enantio-enriched N-sulfonyl-α-amido boronic esters with good yields and excellent enantioselectivities (up to 99% ee).
