## Abstract The chiral amine synthesized from L‐valine methyl ester and 5‐chloro salicylaldehyde proves as good catalyst for the enantioselective oxazaborolidine reduction of prochiral ketones.
## Abstract The effect of borane source on enantioselectivity in the enantiopure oxazaborolidine‐catalyzed asymmetric borane reduction of ketones has been investigated by using (__S__)‐3,1,2‐oxazaborobicyclo[3.3.0]octane and (__S__)‐7,3,1,2‐thiaxazaborobicyclo[3.3.0]octane as catalysts. The results
## Abstract The secondary reduction in the direct and oxazaborolidine‐catalyzed asymmetric borane reduction of ketones was investigated by the use of GC/MS tracing titration and control experiments. The results indicate that the secondary reduction affects the enantioselectivity only in noncoordina
