Abstract
The sponge Haliclona lunisimilis from Point Loma, California, contained six known chlorinated acetylenes, previously isolated from the dorid nudibranch Diaulula sandiegensis, and three new metabolites, (1Z,3Z)-1-chlorohexadeca-1,3-diene-5,7-diyne-14-ol, (1Z,3E,9Z)-15-acetoxy-1-chlorohexadeca-5,7-diyne-1,3,9-triene, and (1Z,3E)-14-acetoxy-1-chlorohexadeca-1,3-diene-5,7-diyne. The structures of the new compounds were elucidated by interpretation of spectroscopic data. The relationship between the sponge metabolites and the nudibranch metabolites is discussed.
