AbstractThe structures and relative sterochemistry of three halogenated sesquiterpenoids gomerones A–C, 1–3, isolated from Laurencia majuscula are described. They are representative of a novel carbon skeleton, gomerane, biogenetically derived from cyclization of a β-chamigrene precursor. A biogenetic relationship with related sesquiterpenoids from lower terrestrial plants Hepaticae of genera Bazzania, Mannia, Mylia, and Rebouli as well as higher plants of genera Cupressus and Juniperus has been established.
