  Stereocontrolled Total Syntheses of Isodomoic Acids G and H via a Unified Strategy

  摘要：

  Marine neuroexcitatory compounds isodomoic acids G and H were efficiently synthesized from a common intermediate using a silicon-based cross-coupling reaction. Dividing each target compound into the core fragment and the side-chain fragment enabled the synthesis to be convergent. The trans-2,3-disubstituted pyrrolidine core fragment was accessed through a diastereoselective rhodium-catalyzed carbonylative silylcarbocyclization reaction of a vinylglycine-derived 1,6-enyne. A stereochemically divergent desilylative iodination reaction was developed to convert the cyclization product to both E- and Z-alkenyl iodides, which would eventually lead to isodomoic acid G and isodomoic acid H, respectively. The late-stage alkenyl alkenyl silicon-based cross-coupling reaction uniting the core alkenyl iodides and the side-chain alkenylsilanol was achieved under mild conditions. Finally, two mild deprotections afforded the target molecules.

• A General Strategy for the Synthesis of Enantiomerically Pure Azetidines and Aziridines through Nickel-Catalyzed Cross-Coupling

  expanded this concept to the synthesis of enantiomerically pure, terminal alkyl aziridines. Coupling of a TMS‐protected aziridine alcohol, followed by acidic work‐up to remove the silyl group, provides 1,2‐amino alcohol products that are readily cyclized to aziridines. Both of these sequences display excellent functional group tolerance and deliver the desired azetidine and aziridine products in good to excellent

  在本交流中，我们报告了对映体纯的2-烷基氮杂环丁烷的直接合成。该规程基于脂族有机锌试剂与具有拴系噻吩基团的氮丙啶的高度区域选择性镍催化交叉偶联。通过甲基化的活化将硫化物转化为极好的离去基团，并通过环化触发2-取代的氮杂环丁烷核心结构的形成。另外，我们已经将该概念扩展到对映体纯的末端烷基氮丙啶的合成。偶联TMS保护的氮丙啶醇，然后进行酸性处理以除去甲硅烷基，可提供1,2-氨基醇产物，这些产物易于环化成氮丙啶。

  The total syntheses of marine natural products belonging to the kainoid family, isodomoic acids G and H, are described. The strategic connection involves a sequential silylcarbocyclization/silicon-based cross-coupling process. These total syntheses were achieved efficiently via a 12- and a 13-step, longest-linear sequence, respectively. The key transformations include a diastereoselective rhodium-catalyzed

  描述了属于 kainoid 家族、isodomoic 酸 G 和 H 的海洋天然产物的全合成。战略联系涉及顺序的甲硅烷基碳环化/基于硅的交叉偶联过程。这些全合成分别通过 12 步和 13 步最长线性序列有效实现。关键转化包括（l）-乙烯基甘氨酸衍生的 1,6-烯炔的非对映选择性铑催化羰基化甲硅烷基碳环化反应、脱甲硅烷基碘化反应以及基于烯基-烯基硅的交叉偶联反应。在研究碘脱甲硅烷基化反应过程中获得的机械洞察力使碘的立体控制引入与双键构型的反转或保留成为可能。
