## Abstract A novel synthetic approach to 2βaryltetralones with high __ee__ has been developed through asymmetric 1,4βaddition of arylboronic acids to naphthoquinone monoketals catalyzed by a rhodium complex with the (__R,R__)βPhβbod\* ligand. The asymmetric addition proceeded in high yields with e
