The reaction of methyl 15-O-acctylisocupressate with SeO2/MeOH yielded, in addition to the expected products of allylic oxidation, ≈20% of selenepanes and selenocanes. The formation of cyclic selenium compounds from diolefins in this reaction is similar to that observed from acetyllinalool. The mechanistic proposal through a double electrophilic attack to both double bonds explains the structural variation
