Abstract
The combination of a highly stereoselective tethered olefin metathesis reaction and a Julia-Kocienski olefination is presented as a strategy for the synthesis of conjugated polyenes with at least one Z-configured C═C bond. The strategy is exemplified by the synthesis of the marine natural product (+)-bretonin B.
