Catalytic reduction of diketones with erythro diphenyl oxazaborolidine yielded C2-symmetric diols in high enantiomeric excess.Enantiomeric excess increased and less meso isomer was generated when borane was employed equimolar with repect to the carbonyl groups and when stoichiometric oxazaborolidine was used.
