• Total Synthesis of Tulearin C
  作者：Konrad Lehr、Ronaldo Mariz、Lucie Leseurre、Barbara Gabor、Alois Fürstner

  日期：2011.11.25

  alkyne metathesis will always be the little brother of alkene metathesis, it allows problems to be solved that are currently beyond reach of the more famous sibling. This notion is exemplified by the tulearin macrolides, which could only be selectively forged by ring‐closing alkyne metathesis (RCAM)/trans reduction using the latest generation of alkyne metathesis catalysts.

  在较小的兄弟的帮助下：尽管炔烃复分解将永远是烯烃复分解的小兄弟，但它可以解决当前更著名的同胞无法解决的问题。牛油蛋白大环内酯类是该概念的例证，其只能通过 使用最新一代炔烃复分解催化剂进行闭环炔烃复分解（RCAM）/反式还原来选择性地伪造。

  日期：2008.10.15

  (+)-lyconadin A (1) and (-)-lyconadin B (2) is presented. Central to this venture was recognition and deployment of a key strategy-level intramolecular aldol/conjugate addition cascade that led, in a single operation, to two new carbon-carbon sigma-bonds, three new stereogenic centers, and two new rings, albeit with the incorrect stereogenicity at C(12) for the lyconadins. Correction of the C(12) stereogenicity

  全面介绍了 (+)-lyconadin A (1) 和 (-)-lyconadin B (2) 的对映选择性全合成。该项目的核心是识别和部署一个关键的战略级分子内醛醇/共轭加成级联，在一次操作中，导致了两个新的碳碳 sigma 键、三个新的立体中心和两个新环，尽管lyconadins 在 C(12) 处的不正确立体性。C(12) 立体性的校正是通过质子化分子内胺的创新使用实现的。氨基碘烯烃环化结合 α-吡啶酮和 3,4-二氢吡啶酮环化方案，分别允许完成 (+)-lyconadin A (1) 和 (-)-lyconadin B (2) 的合成。

The catalytic activities of these chiral polymers were examined by using them as catalysts in the enantioselective desymmetrization of cyclic anhydrides.

  Lactones are known to react with the reagent generated in situ from CCl4 and PPh3 in a Wittig‐type fashion to give gem‐dichloro‐olefin derivatives. Such compounds are now shown to undergo reductive alkylation on treatment with organolithium reagents RLi to furnish acetylene derivatives bearing the substituent R at their termini (R=Me, n‐, sec‐, tert‐alkyl, silyl); the reaction can be catalyzed with
