摘要
The first total synthesis of (+/-)-Celaphanol A was accomplished starting from alpha-cyclocitral and 3,4-dimethoxy benzyl chloride in six steps. The intramolecular cyclization with BF3.Et2O and enolization in t-BuOK/t-BuOH were the key steps. The process of intramolecular cyclization afforded an all-cis isomer intermediate for synthesis of aromatic tricyclic diterpenes.
