title: New carbonimidic dichlorides from the Australian sponge Ulosa spongia and their possible taxonomic significance.
abstract: Five sesquiterpene carbonimide dichlorides (1-5) have been isolated from the dichloromethane extract of the Australian sponge Ulosa spongia. The structures of the two new compounds, ulosins A (1) and B (2), were elucidated by employing spectroscopic techniques (NMR, MS, UV, and IR). The chemotaxonomic significance of our data is discussed.
