Biocatalytic Reduction Reactions from a Chemist's Perspective

Area of Science:

• Organic Chemistry
• Biocatalysis
• Synthetic Chemistry

Background:

• Reductions are fundamental transformations in organic synthesis.
• Enzymatic catalysis offers high selectivity (stereo-, regio-, chemo-) for reduction reactions.
• Enzymes provide greener and potentially shorter synthetic pathways.

Purpose of the Study:

• To review the current state-of-the-art in enzymatic reductions.
• To highlight the potential of enzymes in catalyzing diverse reduction reactions.
• To cover a range of enzymatic reduction types, including carbonyl, enone, aromatic reductions, and reductive aminations.

Main Methods:

• Literature review of enzymatic reduction studies.
• Analysis of enzyme classes and their catalytic mechanisms for reductions.
• Compilation of examples showcasing enzyme applications in synthesis.

Main Results:

• Enzymes demonstrate remarkable selectivity in catalyzing reductions.
• Enzymatic routes can be competitive with or superior to classical methods.
• A broad spectrum of reduction reactions can be achieved using enzymes.

Conclusions:

• Enzymatic reductions are powerful tools for producing chiral molecules.
• Enzymes offer sustainable and efficient alternatives for synthesizing valuable compounds.
• The scope of enzymatic reductions continues to expand, impacting both fine chemicals and bulk chemical production.
