Abstract:	The structures of products obtained by reductive debromination and CF₃COOH- and KOH-induced transformations of natural chamigrane-type sesquiterpenoid (6S,10R)-10-bromo-3,11,11-trimethyl-7-methylidenespiro5,5]undec-2-en-4-one (dactylone) isolated from the sea hare Aplysia dactylomela were analyzed. The absolute configurations of the reaction products were established by CD spectra taking into account the configuration of the starting dactylone.

Keywords:	chamigrane-type sesquiterpenoids terpenoids CD spectra mass spectrometry ¹H and ¹³C NMR spectra mollusc Opisthobranchia sea hare Aplysia dactylomela
