Selective Oxyfunctionalisation Reactions Driven by Sulfite Oxidase-Catalysed In Situ Generation of H₂O₂

H₂O₂ can be accepted by several peroxygenases as a clean oxidant, able to supply both the necessary electrons and oxygen atom at the same time. The biocatalysts, in turn, are able to catalyse an array of interesting oxygen insertion reactions at enantio- and regio-selectivities hard to attain with classical chemical...

FOx News: Towards Methanol-driven Biocatalytic Oxyfunctionalisation Reactions

The novel formate oxidase from Aspergillus oryzae (AoFOx) is a useful catalyst to promote H₂O₂-dependent oxyfunctionalisation reactions. In this contribution we exploit the substrate promiscuity of AoFOx to fully oxidise methanol and formaldehyde to CO₂ and drive peroxygenase-catalysed stereoselective...

Expanding the Spectrum of Light-Driven Peroxygenase Reactions

Peroxygenases require a controlled supply of H₂O₂ to operate efficiently. Here, we propose a photocatalytic system for the reductive activation of ambient O₂ to produce H₂O₂ which uses the energy provided by visible light more efficiently based on the combination of wavelength...

Cascading g-C₃N₄ and Peroxygenases for Selective Oxyfunctionalization Reactions

Peroxygenases are very interesting catalysts for specific oxyfunctionalization chemistry. Instead of relying on complicated electron transport chains, they rely on simple hydrogen peroxide as the stoichiometric oxidant. Their poor robustness against H₂O₂ can be addressed via in situ generation of H₂O<sub>2<...

Peroxygenase-Catalysed Epoxidation of Styrene Derivatives in Neat Reaction Media

Biocatalytic oxyfunctionalisation reactions are traditionally conducted in aqueous media limiting their production yield. Here we report the application of a peroxygenase in neat reaction conditions reaching product concentrations of up to 360 mM.
