Novel eight‐membered heterocycles, named hicksoanes A–C, were isolated from the gorgonian Subergorgia hicksoni . Their structures, including the absolute configuration of all three stereocenters, were determined by means of extensive spectroscopic data. Hicksoanes have a unique structure containing a triazocane cycle, which is substituted by isoleucine and tryptophan moieties. Hicksoanes A–C showed antifeeding activity against goldfish at natural concentration (≈10 μg mL –1 ).(© Wiley‐VCH Verlag GmbH & Co. KGaA, 69451 Weinheim, Germany, 2008)
