brevisamide (1) was isolated from the dinoflagellate Karenia brevis that produces a variety of ladder-frame polyethers. Its proposed biosynthetic intermediate (2) comprising a linear backbone with an E-olefin functionality was synthesized for biosynthetic studies on the marine ladder-frame polyethers.
