A short, high-yielding synthesis of the marine oxylipins constanolactoneA and B was reported. Starting from cinnamyl alcohol (3), the cylopropyl lactone moiety 2 was obtained in 28% yield (11steps). The second coupling partner, vinyl iodide 1,was isolated in 7 steps and 32% yield. Chromium mediatedaddition yielded the natural products as a 2:1 mixture (74%).
