amino ketones - reduction - nickel - scandium

Significance

The authors developed a metal-catalyzed asymmetric reduction of α-amino ketones using KBH4 as hydride source. Under mild conditions, desired amino alcohols are obtained with high enantioselectivities.


 

Comment

β-Amino alcohols are important structural motif in natural or pharmaceutical compounds. The authors also presented a gram-scale version of this reaction and its possible transition state.
