Two labdane-type brominated diterpenes (1 and 2) containing unprecedented seven- and eight-membered ether rings were isolated from the red alga Laurencia ohtusa, collected in Mitikas Bay, Greece. 

Discovered in 2001, prevezols and 3-bromobarekox-ide, which have original carbon skeletons formally related to menthane and labdane, were isolated from Laurencia harvested, respectively, in the Ionian Sea near Preveza (Greece) and in Japan.
