Abstract: | The secondary metabolite chemistry of the red seaweed Laurencia pacifica Kylin varies geographically. The La Jolla, Calif. population (type locality) contains the sesquiterpene prepacifenol, while L. pacifica collected south of Ensenada, Mexico contains a new bromochamigrene derivative, the structure of which is described herein. Since chamigrene synthesis in Laurencia species has been demonstrated to be reasonably species-specific, L. pacifica may be a mixture of morphologically similar forms. |
