    • note
    • Although we did not conduct a systematic study on the effect of the [S]/[Rh] ratio on the optical yields, several control experiments indicated that, for most of the substrates, there is no dependence in the range 100-5000, as previously shown for the hydrogenation of ketopantolactone; see ref 11.
