Engineered myoglobins catalyze asymmetric cyclopropanation reactions, creating valuable carbon-carbon bonds for drug discovery. These biocatalysts offer a scalable and stereoselective method for synthesizing complex cyclopropane structures.
Area of Science:
- Biocatalysis and synthetic chemistry
- Enzyme engineering and directed evolution
Background:
- Biocatalysis is crucial for synthesizing pharmaceuticals and high-value compounds.
- Engineered myoglobins are explored for novel 'abiological' carbene transfer catalysis.
Purpose of the Study:
- Develop myoglobin-based catalysts for asymmetric intermolecular cyclopropanation.
- Expand biocatalytic carbene transfer reactions for new synthetic routes.
Main Methods:
- Engineering myoglobins for carbene transfer catalysis.
- Asymmetric intermolecular cyclopropanation reactions.
- Chemoenzymatic strategies for product diversification.
Main Results:
- Myoglobin catalysts exhibit high stereoselectivity in cyclopropanation.
- Broad substrate scope, scalability, and robustness demonstrated.
- New opportunities for synthesizing functionalized cyclopropanes created.
Conclusions:
- Myoglobin-based systems are valuable for preparative-scale chemical synthesis and biocatalysis.
- Chemoenzymatic strategies provide access to diverse optically active cyclopropane scaffolds.
- These methods are highly relevant for drug discovery and natural product synthesis.

Reduction of Alkenes: Asymmetric Catalytic Hydrogenation
The metal catalyst used can be either heterogeneous or homogeneous. When hydrogenation of an alkene generates a chiral center, a pair of enantiomeric products is expected to form. However, an enantiomeric excess of one of the products can be facilitated using an enantioselective reaction or an...
