    • 5g, and the kinetic control of the reaction imply that the nature of the nucleophiles should not be decisive for the trend of the diastereoselectivity.

    • MM+ Force Field was used for molecular mechanics and Polak-Ribiere algorithm with gradient calculations was adopted for geometry optimization. Semi-empirical electronic total energy estimate and refinement of the geometry were performed with AM1 or PM3 parameter set, depending on the availability of parameters for metal atoms.

    • It has been found that more sterically demanding hydride donors, in the reduction of β-susbtituted ketones, have improved the diastereoselective ratio .
