Abstract:
Historically, biocatalytic ketone reductions involved the use of Baker's yeast. Within the last five years, a significant and growing number of isolated ketoreductases have become available that have rendered yeast-based reductions obsolete. The broad substrate range and exquisite selectivities of these enzymes repeatedly outperform other ketone reduction chemistries, making biocatalysis the general method of choice for ketone reductions. Presented here is a summary of our understanding of the capabilities and limitations of these enzymes.

Alcohols from Carbonyl Compounds: Reduction
Catalytic hydrogenation is similar to the reduction of an alkene or alkyne by adding H2 across the pi bond in the presence of transition metal catalysts like Raney Ni, Pd–C, Pt, or Ru. Aldehydes and ketones can be reduced by this method, often under mild to moderate heat (25–100°C) and...
Preparation of Aldehydes and Ketones from Carboxylic Acid Derivatives
Carboxylic acid derivatives like acid chlorides and esters are more easily reducible than the corresponding acids. The derivatives reduce in the presence of mild reducing agents to give aldehydes. Aldehydes can also be prepared by Rosenmund reduction, that is, the reduction of acid...
