- Abstract
The marine sponge Spongia zimocca S CHMIDT, 1862, collected in front of the torrent II Rogiolo, south of Livorno, contains the sesquiterpene rogiolol acetate (= (+)-(2R, 3S, 6R, 8R, 9R)- 2, 8- dibromo- 9- chloro- 1, 1, 9- trimethyl- 5- methylidenespiro[ 5.5] undec- 3- yl acetate; (+)- 3a), which represents the first chamigrane isolated from a sponge. Although compounds of this class are common in red seaweeds of the genus Laurencia, and our sponge actually contains 9-bromochamigrene and a variety of other metabolites of nearby growing Laurencia sp., (+)- 3a is unique to our sponge.
