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%).
报道了一种短小且高产率的海洋氧脂肪酸化合物constanolactone A和B的合成。从肉桂醇(3)出发,获得了环丙基内酯部分2,产率为28%(共11步)。第二个偶联伙伴,乙烯碘化物1,经过7步合成,产率为32%。铬介导的加成反应生成了自然产物的2:1混合物,产率为74%。
