✦ Synopsis

Two unprecedented nor-sesquiterpenes, austrodoral (4) and its oxidised derivative austrodoric acid (5), have been isolated from the skin of the marine dorid Austrodoris kerguelenensis, collected in Antarctica. The structures and the relative stereochemistry were elucidated on the basis of spectroscopic data. A role of stress-metabolites could be suggested for these compounds.
