title: Sesquiterpene furans and thiosesquiterpenes from the nudibranch Ceratosoma brevicaudatum.
abstract: Six furanosesquiterpenes have been isolated from an Australian nudibranch, Ceratosoma brevicaudatum, and their structures were determined by spectral analysis. The metabolites include the known terpenes dehydrodendrolasin [1], dehydrolasiosperman [3], and thiofurodysinin acetate [7]. The remaining metabolites were determined to be an unreported cis isomer 2 of dehydrodendrolasin, (methylthio) furodysinin [4], and dithiofurodysinin disulfide [5], derivatives of thiofurodysinin acetate that had been isolated earlier from a sponge. 13C-nmr data were obtained for all compounds.
