  • Pd-Catalyzed Decarboxylative Sonogashira Reaction via Decarboxylative Bromination
    作者:Quandi Jiang、Hongyi Li、Xiaofeng Zhang、Biping Xu、Weiping Su

    日期:2018.4.20
    The decarboxylative alkynylation of (hetero)aryl carboxylic acids with terminal alkynes has been achieved by using a Pd(PPh3)4/PCy3 catalyst. This Pd-catalyzed method exhibits good functional group tolerance for both coupling partners and enables chemical modification of complex molecules. The establishment of this decarboxylative alkynylation reaction is attributed to the discovery of a highly selective
    通过使用Pd(PPh 3)4 / PCy 3催化剂,已实现了(杂)芳基羧酸与末端炔烃的脱羧烷基化反应。这种Pd催化的方法对两个偶合伙伴均具有良好的官能团耐受性,并且能够对复杂分子进行化学修饰。该脱羧炔基反应的建立归因于发现了(杂)芳基羧酸与NBS(N-溴代琥珀酰亚胺)的高选择性脱羧溴化。

    An efficient copper-free Sonogashira coupling reaction was performed on water at 100 °C with N,N,N′,N-tetra(diphenylphosphinomethyl)pyridine-2,6-diamine (1) as a ligand, [Pd(η3-C3H5)Cl]2 as a catalyst precursor and K3PO4 as a base. Both aryl and heteroaryl halides were successfully alkynylated in this system, and a high turnover number (TON) up to 860 000 was obtained with a catalyst loading as low

    the alkyne in redox‐neutral annulation with benzamides, with alkyne insertion being stereodetermining. The reaction accommodates both benzamides and heteroaryl carboxamides and proceeds in excellent regioselectivity (if applicable) and enantioselectivities (average 91.8 % ee ). An enantiomerically and diastereomerically pure rhodacyclic complex was prepared and offers insight into enantiomeric control

    Sonogashira reactions, a transition-metal-free version of the arylation of terminal alkynes is elusive. Herein, we report an efficient transition-metal-free Sonogashira-type coupling reaction for the one-pot arylation of alkynes to construct C(sp)–C(sp2) bonds from a tetracoordinate boron intermediate with NIS as a mediator. With its high efficiency, wide substrate range, and good functional group tolerance
    炔烃是有机化学中极具吸引力的合成子。尽管过渡金属催化的 Sonogashira 反应很普遍,但末端炔烃芳基化的无过渡金属版本是难以捉摸的。在此,我们报告了一种有效的无过渡金属的 Sonogashira 型偶联反应,用于炔烃的一锅芳基化,以 NIS 作为介体从四配位硼中间体构建 C(sp)–C(sp 2 ) 键。凭借其高效、广泛的底物范围和良好的官能团耐受性,该方法进一步得到了复杂分子的克级合成和后续修饰的支持。
  • “Nok”: A Phytosterol-Based Amphiphile Enabling Transition-Metal-Catalyzed Couplings in Water at Room Temperature
    作者:Piyatida Klumphu、Bruce H. Lipshutz
    DOI:10.1021/jo401744b
    日期:2014.2.7
    The third-generation designer amphiphile/surfactant, "Nok" (i.e., SPGS-550-M; beta-sitosterol methoxypolyethyleneglycol succinate), soon to be commercially available from Aldrich, can be prepared in two steps using an abundant plant feedstock and beta-sitosterol, together with succinic anhydride and PEG-550-M. Upon dissolution in water, it forms nanomicelles that serve as nanoreactors, which can be characterized by both cryo-TEM and dynamic light scattering analyses. Several transition-metal-catalyzed reactions have been run under micellar conditions to evaluate this surfactant relative to results obtained in nanoparticles composed of TPGS-750-M (i.e., a second-generation surfactant). It is shown that Nok usually affords yields that are, in general, as good or better than those typically obtained with TPGS-750-M, and yet is far less costly.
