Figure 4: Aerobic Achmatowicz oxidation of 2,5-disubstituted furans.
From: Enzymatic aerobic ring rearrangement of optically active furylcarbinols

On the basis of the enzyme cascade consisting of an oxidase and a lipase, peracetic acid is formed catalytically from the acetate buffer that can act as diffusible redox mediator in the oxidation of otherwise non-reactive furylcarbinols.
