A collection of Laurencia elata from the coast of Victoria has provided the pyrano[3,2-7>]pyranyl vinyl acetylene elatenyne (666) (772), which is related to the known (Z)-dactomelyne (7). Japonenynes A (667), B (668), and C (669), which possess a furo[3,2-h]pyranyl framework, were isolated from Laurencia japonensis (773). Compound 669 may be an isolation (methanol) artifact although it is isolated as a single compound. The report of aplysiallene from the sea hare Aplysia kurodai (774) is erroneous and this compound is actually a known bromoallene (775) described earlier (7). The Vietnamese Laurencia pannosa contains pannosallene (670), which is closely related to the known laurallene...

The red algal chamigrene sesquiterpene elatol (Structure 2.78) has been shown to deter feeding by reef fishes.93 Specimens of Laurencia elata from Southern Australia show a pronounced seasonal variation in elatol production. Incorporation studies using 14C acetate failed to confirm an acetate-mevalonate path for elatol production.125... 

Interest continues in the isolation and structural elucidation of halogenated sesquiterpenoids produced by marine organisms (e.g. algae). Many of these compounds are chamigrane derivatives and new members of this group include prepacifenol epoxide (89)46 from Aplysia californica, elatol (90)47 from Laurencia elata, nidifidienol (91)48 from Laurencia nidifica, and the compounds (92) and (93)49 from...
