Deuterium labelling experiments have shown that acid catalysed reaciton of endo-tricyclo[3.2.1.02,4]oct-6-ene with methanol proceeds exclusively by cyclopropyl corner protonation followed by skeletal rearrangement to an allylic ion and formation of 2-exo-methoxybiocyclo[3.2.1]oct-3-ene.
氘标记实验表明,
三环内环[3.2.1.0 2,4 ] oct-6-ene与
甲醇的酸催化反应仅通过环丙基角质子化,然后骨架重排成烯丙基离子并形成2-exo-甲氧基
生物环[3.2.1] oct-3-ene。
