Preparation of Optically Active Deuterated Primary Alcohols: Enantioselective Borodeuteride Reduction of Aldehydes Catalyzed by Cobalt Complexes.

The enantioselective borodeuteride reduction of aldehydes catalyzed by optically active β-ketoiminato cobalt complexes afforded the corresponding chiral deuterated primary alcohols with a high degree of deuteration and good enantiomeric excess.
