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
15- O-乙酰异癸酸甲酯与SeO 2 / MeOH的反应除产生烯丙基氧化的预期产物外,还产生≈20%的硒烷和硒烯。在该反应中由二烯烃形成环状硒化合物与从乙酰基芳樟醇中观察到的类似。通过对两个双键进行双亲电攻击的机理建议解释了在此情况下和以前情况下含硒产品的结构变化。
