  • An Enyne Cope Rearrangement Enables Polycycloalkane Synthesis from Readily Available Starting Materials
    作者:Sarah K. Scott、Alexander J. Grenning
    DOI:10.1002/anie.201703186
    日期:2017.7.3
    Knoevenagel adducts (cyclohexylidenemalononitriles) and two different propargyl electrophiles serve as carbon sources for assembling diverse 6/7/5 tricycloalkanes, a common terpenoid framework. The sequence involves three unique reactions: 1) deconjugative propargylation, 2) one‐pot enyne Cope rearrangement/deconjugative propargylation, and 3) an allenic Pauson–Khand reaction.
    环己酮衍生的Knoevenagel加合物(环己叉基丙二腈)和两种不同的炔丙基亲电试剂可作为碳源来组装各种6/7/5三环烷烃(一种常见的萜烯骨架)。该序列涉及三个独特的反应:1)去共轭炔丙基化; 2)单罐烯炔应对反应重排/去共轭炔丙基化; 3)烯丙基Pauson-Khand反应。

  • Transient [3,3] Cope rearrangement of 3,3-dicyano-1,5-dienes: computational analysis and 2-step synthesis of arylcycloheptanes

    reported. The two-step route from Knoevenagel adducts and allylic electrophiles is made possible through the design of a Cope rearrangement that utilizes a “traceless” activating group to promote an otherwise thermodynamically unfavorable transformation. Experimentally, the [3,3] rearrangement occurrs transiently at room temperature with a computed barrier of 19.5 kcal mol−1, which ultimately allows for three-component
    报道了一种简单且模块化的芳基环庚烯支架路线。通过 Cope 重排的设计,从 Knoevenagel 加合物和烯丙基亲电子试剂的两步路线成为可能,该重排利用“无痕”活化基团来促进热力学上不利的转变。实验上,[3,3]重排在室温下瞬时发生,计算出的势垒为19.5 kcal mol -1,最终允许三组分双烯丙基化。闭环复分解产生芳基环庚烷并除去活化基团。本报告描述了方法、范围和机制研究以及计算分析的设计和优化。
