Biosynthesis of cyclic ketones by a H2O2 self-sufficient cascade reaction

In the present work we propose a bienzymatic cascade for the oxyfunctionalisation of cycloalkanes to cyclic alcohols/cyclic ketones. By combining a H 2 O 2 -dependent peroxygenase with a O 2 -consuming and H 2 O 2 -producing alcohol oxidase an overall aerobic oxidation system was established. A convincing proof-of-concept is presented and some current limitations are outlined.
