An improved synthesis of (-)-brevisamide a marine cyclic ether isolated from the red-tide dinoflagellate Karenia brevis was achieved. The ether ring portion was constructed from an unsaturated lactone, which was prepared enantioselectively via an Evans aldol reaction and one-pot lactonization in the presence of excessive base after an Ando reaction. The ether ring and a dienol side chain fragment were connected via Suzuki-Miyaura coupling.

A convergent synthesis of brevisamlde (1) is described based on the application of the crotyl silane-based [4 + 2]-annulatlon used for the preparation of the advanced oxygenated tetrahydropyran Intermediate 2. The side chain bearing a conjugated (E,E)-die
