2,6- Cyclo-xenicanes from the brown algae Dilophus fasciola and Dilophus spiralis

Seven new diterpenes, featuring the rare 2,6- cyclo-xenicane skeleton, along with eleven previously reported metabolites were isolated from the organic extracts of the brown algae Dilophus fasciola and Dilophus spiralis. The structure elucidation of the isolated natural products was based on detaile...

Zusammenfassung:Seven new diterpenes, featuring the rare 2,6- cyclo-xenicane skeleton, along with eleven previously reported metabolites were isolated from the organic extracts of the brown algae Dilophus fasciola and Dilophus spiralis. The structure elucidation of the isolated natural products was based on detailed analyses of their spectroscopic data (NMR, MS, IR, UV), whereas the assignment of their relative configurations was assisted by molecular modelling studies.
