  • Interligand Interactions Dictate the Regioselectivity of<i>trans</i>-Hydrometalations and Related Reactions Catalyzed by [Cp*RuCl]. Hydrogen Bonding to a Chloride Ligand as a Steering Principle in Catalysis
    作者:Stephan M. Rummelt、Karin Radkowski、Dragoş-Adrian Roşca、Alois Fürstner

    mode in the presence of [Cp*Ru(MeCN)3]PF6 (1) as the catalyst; however, the regioselectivity is often poor with unsymmetrical substrates. This problem can be solved upon switching to a catalyst comprising a [Ru-Cl] bond, provided that the acetylene derivative carries a protic functional group. The R3M unit is then delivered with high selectivity to the alkyne-C atom proximal to this steering substituent
    在 [Cp*Ru(MeCN)3]PF6 (1) 作为催化剂的存在下,内炔与 R3M-H(M = Si、Ge、Sn)的反应遵循非常规的反式加成模式;然而,不对称底物的区域选择性通常很差。如果乙炔生物带有质子官能团,则该问题可以通过改用包含 [Ru-Cl] 键的催化剂来解决。然后,R3M 单元以高选择性传递到该控制取代基附近的炔烃-C 原子。这种导向效应源于极化的 [Ru-Cl] 键与质子取代基进行氢键合的能力,这有助于将炔烃上传、激活和锁定在配位球内。化物与 -MR3 中心的额外配位体接触将进入的试剂定位在匹配的方向,从而转化为高区域选择性。所提出的负载催化剂内的二次相互作用与大量制备和光谱数据以及固态新型 π 配合物 10 和 11 的结构一致。此外,还提出了 [Ru(σ-烷)] 配合物 (12a) 的第一个 X 射线结构,它确实具有外围 Ru-Cl……MR3 接触;该加合物也证实炔烃反式加成化学可能涉及
  • Au-Containing All-Carbon 1,3-Dipoles: Generation and [3+2] Cycloaddition Reactions
    作者:Guozhu Zhang、Liming Zhang
    DOI:10.1021/ja804690u
    日期:2008.9.24
    novel approach to generate Au-containing all-carbon 1,3-dipoles is developed via an unprecedented migration-fragmentation of ketals/acetals. These in situ generated dipoles undergo rapid [3+2] cycloaddition under mild conditions with various enones/enals, electron-rich aromatic aldehydes, and N-benzylindole, leading to flexible formation of highly functionalized dihydrofurans and cyclopentenes.
    通过缩酮/缩醛的前所未有的迁移断裂,开发了一种产生含全碳 1,3-偶极子的新方法。这些原位生成的偶极子在温和条件下与各种烯酮/烯醛、富电子芳香醛和 N-苄基吲哚发生快速 [3+2] 环加成,从而灵活地形成高度官能化的二氢呋喃环戊烯

  • Regioselective Pd-catalyzed alkylative lactonizations of 4-hydroxy-2-alkynecarboxylates with organoboronic acids
    作者:Chang Ho Oh、Su Jin Park、Jin Hyang Ryu、Arun Kumar Gupta
    DOI:10.1016/j.tetlet.2004.07.129
    日期:2004.9
    The palladium-catalyzed addition of aryl- and alkenylboronic acids to 4-hydroxy-2-alkynecarboxylates and in situ lactonization would constitute a novel methodology for the synthesis of various butenolides with an excellent stereoselectivity and a high control of regioselectivity.
