Abstract
| - Seven new diterpene isonitriles and isothiocyanates were isolated from the sponge Phakellia pulcherrimaalong with eight known ones. Six of the new compounds, 9−14, and the eight known ones, 1−8, belongto the kalihinol family of diterpenes. Structures were determined from spectroscopic data. This is thefirst report of diterpenes from sponges of this genus. All of the other kalihinol diterpenoids have beenisolated from the sponge Acanthella cavernosa collected in diverse locations.
