A concise total synthesis of the marine sponge metabolite spongian-16-one 1, which features a novel cascade of three consecutive 6-endo-trig radical cyclisations from a polyene acyl radical intermediate as a key step, viz9 → 10, is described.
描述了一种简单的海洋海绵代谢产物spongian-16-one 1的简要合成过程,该过程的特征是从多烯酰基自由基中间体开始的三个连续的6-内-trig自由基环化的新级联反应,这是关键步骤,即9→10。
