Abstract:
The hydrocarbon fraction of the liverwort Trocholejeunea sandvicensis was investigated. Four new sesquiterpene hydrocarbons including the trifaranes (-)-trifara-9,14-diene (6) and (-)-3,7-di-epi-3,7-trifara-9,14-diene (7), as well as (+)-sandvicene (8), a sesquiterpene with uncommon skeleton, and the rearranged trifarane sesquiterpene (+)-neotrifaradiene (9) were isolated and their structure elucidated. A biogenetic pathway for the four compounds is proposed, with nerolidol as their common precursor.

Structure of Conjugated Dienes
Conjugated dienes are compounds characterized by the presence of alternating double and single bonds. In a conjugated system like 1,3-butadiene, the unhybridized 2p orbital on each carbon overlaps continuously, allowing the π electrons to be delocalized across the entire molecule. In contrast, this type of overlap does not occur in cumulated and isolated dienes, such as 2,3-pentadiene and 1,4-pentadiene, respectively. Instead, the π electrons remain localized between the double...
