The use of chiral BINAM NHC-Rh(III) complexes in enantioselective hydrosilylation of 3-oxo-3-arylpropionic acid methyl or ethyl esters

Axially chiral BINAM N-heterocyclic carbene (NHC)-Rh-(III) complexes were applied in the enantioselective hydrosilylation of 3-oxo-3-arylpropionic acid methyl or ethyl esters. The reduction products 3-hydroxy-3-arylpropionic acid methyl or ethyl esters could be obtained in good yields with good to excellent enantioselectivities under mild conditions.
