The Baeyer–Villiger oxidation of 3 and 17-ketosteroids by a recombinant
cyclopentadecanone monooxygenase from Pseudomonas
sp. was reported to yield the corresponding lactones with a
full control of the regiochemistry, albeit with moderate yields
(Beneventi et al., 2009). NADPH was used as cofactor and recycled
in situ by D-glucose-6P oxidation to D-gluconate-6P by glucose 6-
phosphate deshydrogenase
