✦ Synopsis

6S,10S)-3,10- Dimethyl-7,11-dimethylidenespiro[5,5]undec-2-en-4-one (1), a new rearranged chamigrane-type sesquiterpenoid with two sp 2 -hybridized carbons in α-positions to the spiro-atom, was isolated from the alcoholic extract of the sea hare Aplysia sp. and its structure and absolute configuration were established by chemical transformations, NMR, EIMS, IR, UV and CD spectroscopy.
