Abstract
(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 ca rbons in alpha-positions to the spiro-atom, was isolated from the alcoholic extract of the sea hare Aplysia sp. and its structure and absolute configu ration were established by chemical transformations, NMR, EIMS, IR, UV and CD spectroscopy.
