Iron‐Catalyzed Ring‐Opening/Allylation of Cycloalkyl Hydroperoxides with Allylic Sulfones

Abstract An efficient iron‐catalyzed allylation of cycloalkyl hydroperoxides with allylic sulfones via C−C bond cleavage is presented. This protocol provides an efficient approach to a wide range of distally allylated ketones with good functional group tolerance and high regioselectivity under redox‐neutral conditions. Preliminary mechanistic study implies a radical process might be involved in this reaction.
