be diverted to catalytic, mixed hydroxylase/desaturase activity with aliphatic C–H bonds. Using a taxane-based radical trap that rearranges under Fe(PDP) oxidation to furnish a nortaxane skeleton, we provide the first direct evidence for a substrate radical using this class of stereoretentive hydroxylation catalysts. Hydroxylation and desaturation proceed by means of a short-lived radical that diverges
