Construction of the tricyclic derivative 5, a common intermediate for the synthesis of sesquiterpenoids 1–4, was accomplished by using the intramolecular Diels–Alder reaction. Availability of 5 was demonstrated by effective total synthesis of chiloscyphone 1 and isochiloscyphone 2.
三环衍生物的结构5,为倍半萜的合成共同中间体1 - 4,通过使用分子内Diels-Alder反应来完成的。通过有效合成Chiloscyphone 1和isochiloscyphone 2证明了5的可用性。
