A mild, enantioselective hydrosilylation of 3-oxo-3-arylpropionic acid methyl or ethyl esters using axially chiral BINAM N-heterocyclic carbene (NHC)-Rh(III) complexes as catalysts gave 3-hydroxy-3-arylpropionic acid methyl or ethyl esters in good yields with good to excellent enantioselectivities under mild conditions.
