A new modified furanoeremophilane type sesquiterpene, (+)-14-methoxy-1,2-dehydrocacalol methyl ether (2), isolated from Trichilia cuneata exhibited inhibitory activity for mitochondrial lipid peroxidation. The first total synthesis of (±)-2 and two related sesquiterpenes, (±)-14-hydroxycacalol methyl ether (7) and 14-methoxydehydrocacalohastine (8), has also been achieved.
