products, e.g. lophotoxins, pukalides, bipinnatins, based on: i) an intramolecular cyclisation of an alpha,beta-unsaturated acyl radical intermediate into a conjugated enone, and ii) an intramolecular Stille coupling reaction involving a 2-stannylfuran and a vinyl iodide, are described. A total synthesis of bis-deoxylophotoxin , the probable biological precursor to the neurotoxin lophotoxin, isolated from
合成呋喃膜家族天然产物(例如光致毒素,普卡利特,联吡啶类)的方法,基于:i)α,β-不饱和酰基自由基中间体的分子内环化成共轭烯酮,和ii)涉及a的分子内Stille偶联反应描述了2-锡烷基呋喃和乙烯基碘。然后介绍了双脱氧光合毒素的全合成,这是从太平洋海鞭Lophogorgia物种中分离出来的神经毒素低光合毒素的生物学前体。
