Abstract Two new sesquiterpenoid metabolites have been characterized from a Jamaican variety of the marine alga Laurencia obtusa. These are 2-chloro-3-hydroxy-α-chamigren-9-one, with an unusual cis-relationship of the heteroatoms at the 2,3-positions, and its intramolecular conjugate addition derivative possessing a cineole moiety fused to a cyclohexane ring.
