Microbial hydroxylation of steroids. 10. Rearrangement during epoxidation and hydroxylation, and the stepwise nature of these enzymic reactions

A series of unsaturated steroids has been incubated with fungi which are known to hydroxylate at a site corresponding to the allylic position in the analogous saturated steroids.In some cases, the anticipated hydroxylation occurred without rearrangement of the double bond.In a number of instances, however, products were obtained whose structures implied that allylic rearrangement had occurred during the reaction.The formation of these products is consistent with a stepwise mechanism of enzymatic oxidation.Possible routes for product formation are presented which incorporate this proposal.
