pectenotoxin-2 (PTX-2) is described that features a stereoselective annulation to generate the C-ring by triple asymmetric Nozaki–Hiyama–Kishi coupling followed by oxidative cyclization. Preparation of the C1–C14 AB spriroketal-containing subunit employs a recently developed metallacycle-mediated reductive cross-coupling between a TMS-alkyne and a terminal alkene.
描述了 pectenotoxin-2 (PTX-2) 的 C1-C26 六环亚基的合成,该亚基具有立体选择性环化,通过三重不对称 Nozaki-Hiyama-Kishi 偶联随后氧化环化生成 C 环。含 C1-C14 AB 螺旋缩酮亚基的制备采用最近开发的金属环介导的 TMS-炔烃和末端烯烃之间的还原交叉偶联。
