The first total synthesis of koshikalide, a 14-membered macrolide that contains three olefins, was achieved. The skipped diene in the cyclic system was efficiently constructed by very mild Stille coupling at low temperature. The absolute stereochemistry was established by comparison of the specific optical rotations of natural and synthesized koshikalide.
