Polybrominated non-terpenoid C-15 compounds from Laurencia paniculata and Laurencia obtusa

Abstract

Two polybrominated C-15-acetogenins (1,2) isolated from a Mediterranean sponge previously and a new polybrominated bicyclic ether with a bromoallenic side chain (3) were isolated from Laurencia paniculata and Laurencia obtusa respectively. The structures of these compounds were elucidated by spectroscopic methods.
