blue-sensitized photooxygenation of several α-cyclogeranyl derivatives affords the exocyclic allylic hydroperoxides in 94-99% regioselectivity, while the diastereoselectivity varies from 50-97% de in favor of the cis isomer, depending on the substituents. By contrast, the enereaction with N-phenyltriazol-inedione affords significantly different regioselectivity and diastereoselectivity.
