Chlorosulfolipids and the Corresponding Alcohols from the Octocoral Dendronephthya griffini

Two new polychlorolipids, namely, (2R,3S,4R,5S,6S,7R)-2,3,5,6,7-pentachloropentadec-14-en-4-yl hydrogen sulfate (2) and (2R,3S,4R,5S,6S,7R)-2,3,5,6,7-pentachloropentadec-14-en-4-ol (4), along with a known chlorosulfolipid (1), were isolated from the octocoral Dendronephthya griffini. (2R,3S,4R,5S,6S,7R,E)-2,3,5,6,7,15-Hexachloropentadec-14-en-4-ol (3) was isolated for the first time from a natural source. The structures of these compounds were elucidated by extensive spectroscopic analysis and by comparison of the NMR data with those of known compound 1. This type of compound was isolated for the first time from the soft corals.
