    frustration of H2O2, the parent peroxide, where the lone pairs of oxygen are not involved in strongly stabilizing orbital interactions. Computational analysis reveals how this frustration is relieved in the tricyclic peroxide products, where strongly stabilizing anomeric nO→σC-O* interactions are activated. The calculated potential energy surfaces for these transformations combine labile, dynamically formed
    我们描述了一种有效的单锅程序,该程序将无环三酮“折叠”成结构复杂的药物相关三环系统,该系统将高氧含量与异常稳定性相结合。特别是β,γ'-三酮在酸催化下在H2O2存在下转化为三维多环过氧化物。这些转变是由 H2O2(母体过氧化物)的立体电子受阻推动的,其中孤对氧不参与强烈稳定的轨道相互作用。计算分析揭示了如何在三环过氧化物产品中缓解这种挫败感,其中强烈稳定的异头 nO→σC-O* 相互作用被激活。这些转换的计算势能面结合了不稳定的、动态形成的阳离子物质具有深度稳定的中间结构,对应于引入一个、两个或三个过氧化物部分。矛盾的是,随着过氧化物产物的热力学稳定性沿着反应级联增加,它们形成的动力学障碍也增加。反应势能表面的这一特征允许分离单过氧化物和双过氧化物三环产物,这也解释了为什么最稳定的三过氧化物的形成在动力学上最不可行并且没有在实验中观察到。这种独特的行为可以通过“逆α效应”来解释,这是一种新

  • Rapid assembly of complex cyclopentanes employing chiral, α,β-unsaturated acylammonium intermediates

    With the intention of improving synthetic efficiency, organic chemists have turned to bioinspired organocascade or domino processes that generate multiple bonds and stereocentres in a single operation. However, despite the great importance of substituted cyclopentanes, given their prevalence in complex natural products and pharmaceutical agents, the rapid, enantioselective assembly of these carbocycles lags behind cyclohexanes. Here, we describe a Michael–aldol-β-lactonization organocascade process for the synthesis of complex cyclopentanes utilizing chiral α,β-unsaturated acylammonium intermediates, readily generated by activation of commodity unsaturated acid chlorides with chiral isothiourea catalysts. This efficient methodology enables the construction of two C–C bonds, one C–O bond, two rings and up to three contiguous stereogenic centres delivering complex cyclopentanes with high levels of relative and absolute stereocontrol. Our results suggest that α,β-unsaturated acylammonium intermediates have broad utility for the design of organocascade and multicomponent processes, with the latter demonstrated by a Michael–Michael–aldol-β-lactonization. Despite their appearance in a number of bioactive natural products, the synthesis of 5-membered carbocycles has received much less attention than synthesis of their 6-membered counterparts. Here, a Michael-aldol-β-lactonization cascade is used to forge two C-C bonds, one C-O bond, two rings and up to three contiguous stereocentres and deliver complex cyclopentanes with high levels of relative and absolute stereocontrol.
    为了提高合成效率,有机化学家转而采用生物启发的有机级联或多米诺过程,在一次操作中生成多个键和立体中心。然而,尽管取代的环戊烷在复杂的天然产品和药物制剂中非常普遍,具有重要意义,但这些碳环的快速对映选择性组装却落后于环己烷。在这里,我们介绍了利用手性δ,δ²-不饱和酰基铵中间体合成复杂环戊烷的迈克尔-醛-δ-内酯化有机级联工艺,这种中间体可通过手性异硫脲催化剂活化商品不饱和酸氯化物而生成。这种高效的方法可以构建两个 CâC 键、一个 CâO 键、两个环和多达三个连续的立体中心,从而提供具有高度相对和绝对立体控制能力的复杂环戊烷。我们的研究结果表明,δ,δ-不饱和酰基铵中间体在设计有机级联和多组分过程中具有广泛的用途,后者通过迈克尔-迈克尔醛-δ-内酯化过程得到了证明。尽管五元碳环出现在许多具有生物活性的天然产物中,但其合成所受到的关注却远远低于六元碳环的合成。在这里,我们利用迈克尔-醛-δ-内酯化级联法生成了两个 C-C 键、一个 C-O 键、两个环和多达三个连续的立体中心,并提供了具有高水平相对和绝对立体控制的复杂环戊烷。
