Abstract
Two sponges of the genus Hyrtios have been found to contain new sesquiterpene/quinones identified by detailed spectroscopic analysis. Four new compounds with a 4,9-friedodrim-3-ene skeleton [hyrtiophenol (2), 5-epihyrtiophenol (3), 18-hydroxy-5-epihyrtiophenol (4), and 18-hydroxyhyrtiophenol (5)] were isolated from Hyrtios sp. (Seychelles Islands) along with isospongiaquinone (1). Moreover, the new compound 21-hydroxy-19-methoxyarenarone (8), which bears the 4,9-friedodrim-4(15)-ene skeleton, was isolated from Hyrtios tubulatus (Curaçao) along with arenarol (6) and 5-epiilimaquinone (7). Assignment of the 13C NMR signals of four types of 4,9-friedodrimene skeletons found in sponges is presented.Keywords
