Recent Developments in Oxidative Biocatalytic Cascades

Biocatalytic cascades that involve enzymatic oxidation as one or more key steps are powerful tools to access valuable chemicals with various functionalizations starting from simple substrates, without the isolation of intermediates. This review discusses the recent advances in oxidative cascades, with perspectives given on the current limitations and future developments. The strategies employed to achieve efficient supply of redox cofactors are also highlighted. The examples include cascades that begin with alkene epoxidation, alkane hydroxylation, alcohol oxidation or amine oxidation. These oxidative steps are followed by a variety of enzyme-catalyzed functionalizations, producing a diverse range of high-value products.
