A highly stereoselective and enantioselective reduction of racemic spiro[4.4]nonane-1,6-dione catalyzed by an oxazaborolidine reagent is described. The asymmetric reduction of the racemic spirodiketones resulted in enantiomerically pure spirodiols which are useful chiral auxiliaries and also key int
