  • Highly Enantioselective Cobalt‐Catalyzed (3+2) Cycloadditions of Alkynylidenecyclopropanes
    作者:Eduardo Da Concepción、Israel Fernández、José L. Mascareñas、Fernando López
    DOI:10.1002/anie.202015202
    日期:2021.4.6
    Low‐valent cobalt complexes equipped with chiral ligands can efficiently promote highly enantioselective (3+2) cycloadditions of alkyne‐tethered alkylidenecyclopropanes. The annulation allows to assemble bicyclic systems containing five‐membered rings in good yields and with excellent enantiomeric ratios. We also present a mechanistic discussion based on experimental and computational data, which support
    配备手性配体的低价钴络合物可以有效地促进炔烃系链的亚烷基环丙烷的高对映选择性(3 + 2)环加成反应。该环状结构可以以高收率和出色的对映体比率组装包含五元环的双环系统。我们还提出了基于实验和计算数据的机制讨论,这些讨论支持Co I / Co III催化循环的参与。
  • Nickel-Catalyzed [3+2+2] Cycloadditions between Alkynylidenecyclopropanes and Activated Alkenes
    作者:Lucía Saya、Gaurav Bhargava、Miguel A. Navarro、Moises Gulías、Fernando López、Israel Fernández、Luis Castedo、José L. Mascareñas

    日期:2010.12.17
    Now with nickel: [3C+2C+2C] cycloadditions involving non‐activated alkylidenecyclopropanes provide a practical entry to a variety of interesting 6,7‐fused bicyclic systems (see scheme; cod=1,5‐cyclooctadiene). DFT calculations, combined with experimental data, suggest that the catalytic cycle involves the initial formation of 1‐alkylidenenickelacyclobutane intermediates, such as 1.

  • Ruthenium-Catalyzed [3 + 2] Intramolecular Cycloaddition of Alk-5-ynylidenecyclopropanes Promoted by the “First-Generation” Grubbs Carbene Complex
    作者:Fernando López、Alejandro Delgado、J. Ramón Rodríguez、Luis Castedo、José L. Mascareñas
    DOI:10.1021/ja0480466
    日期:2004.8.1
    The well-known "first generation" Grubbs metathesis complex is capable of catalyzing the intramolecular [3 + 2] cycloaddition of alk-5-ynylidenecyclopropanes. It appears that the species responsible for the catalysis is a ruthenium complex generated in situ from the Grubbs carbene in the presence of the substrate.
    众所周知的“第一代”Grubbs 复分解复合物能够催化 alk-5-ynylidenecyclopropanes 的分子内 [3 + 2] 环加成。似乎负责催化的物质是在底物存在下从格鲁布斯卡宾原位生成的钌络合物。

    作者:Alejandro Delgado、J. Ramón Rodríguez、Luis Castedo、José L. Mascareñas
    DOI:10.1021/ja0356333
    日期:2003.8.1

  • Divergent reactivity of alk-5-ynylidenecyclopropanes in the presence of the 1st or the 2nd generation Grubbs’ catalysts
    作者:Beatriz Trillo、Moisés Gulías、Fernando López、Luis Castedo、José L. Mascareñas
    DOI:10.1016/j.jorganchem.2005.07.009
    日期:2005.12
    Alk-5-ynylidenecyclopropanes, by virtue of being equipped with a strained cyclopropane system, can be divergently elaborated into bicyclo[3.3.0]octenes or exocyclopropylidenecycloalkenes depending on whether they react with the first or the second generation Grubbs' ruthenium carbenes. While the highly reactive second generation system catalyses the formation of ring-closing metathesis products, the less [metathesis] active first generation carbene promotes an intramolecular [3 + 2] cycloaddition to give the bicarbocyclic skeletons.
