  • Influence of Biaryl Phosphine Structure on C−N and C−C Bond Formation

    phosphine ligands affect Pd-catalyzed C-N and C-C bond-forming reactions, a new ligand, 2-(dicyclohexylphosphino)-4'-(N,N-dimethylamino)-1,1'-biphenyl, was synthesized. This compound is isomeric with the commercially available 2-(dicyclohexylphosphino)-2'-(N,N-dimethylamino)-1,1'-biphenyl that has been useful in C-N bond-forming reactions of nucleosides. The new p-dimethylamino biphenyl ligand bears
    为了了解联苯膦配体的电子和其他结构特征如何影响 Pd 催化的 CN 和 CC 键形成反应,一种新的配体,2-(二环己基膦)-4'-(N,N-二甲氨基)-1,1 '-联苯,合成。该化合物与市售的 2-(二环己基膦基)-2'-(N,N-二甲氨基)-1,1'-联苯异构,后者已用于核苷的 CN 键形成反应。新的对二甲氨基联苯配体与邻二甲氨基异构体具有电子相似性,但它也具有与 2-(二环己基膦基)联苯的结构相似性,例如非膦环中未取代的邻位。而 2-(二环己基膦基)联苯可以支持形成 CC 键的催化剂,它不能有效地促进核苷底物的芳基胺化。然而,新的配体被证明可以有效地促进核苷底物的芳基胺化和 CC 键形成反应,一些反应甚至在室温下发生。因此,这种新配体的复合结构元素被认为是由它衍生的催化系统反应性的标准。我们已经通过 X 射线晶体学分析探测了异构 N,N-二甲氨基联苯配体的结构。已通过 (31) P 核磁共振研究了两种配体与
  • Facile Cu-free Sonogashira cross-coupling of nucleoside C-6 arylsulfonates with terminal alkynes

    The combination of PdCl2[CH3CN]2 with XPhos is an efficient catalytic system for the Sonogashira-type cross-coupling of 2′-deoxyguanosine O6-arylsulfonates with terminal alkynes. The reactions generally proceed under mild conditions requiring no Cu co-catalyst to give the corresponding C-6-alkynylated deoxynucleosides in moderate to good yields.
    PdCl 2 [CH 3 CN] 2与XPhos的结合是2'-脱氧鸟苷O 6-芳基磺酸盐与末端炔烃的Sonogashira型交叉偶联的有效催化体系。反应通常在温和的条件下进行,不需要Cu助催化剂以中等至良好的产率得到相应的C-6-炔基化的脱氧核苷。
  • Mild and Room Temperature C−C Bond Forming Reactions of Nucleoside C-6 Arylsulfonates
    作者:Mahesh K. Lakshman、Padmaja Gunda、Padmanava Pradhan

    日期:2005.12.1
    Palladium catalyzed cross coupling of nucleoside arylsulfonates and arylboronic acids has been accomplished under mild conditions and at room temperature. Among three structurally similar ligands that differ in their steric and electronic properties, one yielded an effective catalyst in conjunction with Pd(OAc)2. Of the nucleoside arylsulfonates evaluated, the O6-(2,4,6-trimethylphenyl)sulfonate proved
    钯催化的核苷芳基磺酸盐和芳基硼酸的交叉偶联已在温和条件和室温下完成。在三种结构相似,空间和电子性质不同的配体中,一个配体与Pd(OAc)2结合产生了一种有效的催化剂。在所评估的核苷芳基磺酸盐中,O 6-(2,4,6-三甲基苯基)磺酸盐被证明是最佳的,但其他烷基和烷氧基衍生物也具有合理的反应性。另一方面,2-硝基苯基和2-噻吩基衍生物是无效的底物。PhMe和THP适合用作溶剂,尽管在PhMe中某些芳基硼酸的反应更快,但在某些情况下仍能获得良好的结果。相反,带有强吸电子基团的芳基硼酸的反应在THP中更成功地进行。包括核苷芳基磺酸盐上的取代基,配体取代基和溶剂在内的几种因素之间的相互作用是成功进行交叉偶联的原因。使用31 P NMR进行了初步研究,以研究Pd(OAc)2的相互作用与配体。在配体和Pd(OAc)2的化学计量比为1:1的情况下,获得了主要物质,可能是环palpalladation的产

    作者:Fumi Nagatsugi、Yuki Ogata、Shuhei Imoto、Shigeki Sasaki
    DOI:10.3987/com-07-s(u)24

    6-Substituted purine analogs function in a variety of biological activities including antiviral pathways. A number of studies have reported on the development of the efficient synthesis of these nucleoside analogs. We previously demonstrated that oligonucleotides containing 2-amino-6-vinylpurine derivatives react with the cytosine at the target site with extreme selectivity. This was the first finding
    6-取代的嘌呤类似物在包括抗病毒途径在内的多种生物活性中起作用。许多研究报告了这些核苷类似物的有效合成的发展。我们之前证明了含有 2-氨基-6-乙烯基嘌呤衍生物的寡核苷酸与靶位点的胞嘧啶反应具有极高的选择性。这是鸟苷的O 6 -甲苯磺酸酯衍生物作为Pd(0)催化的与乙烯基三丁基锡烷的交叉偶联反应产生2-氨基-6-乙烯基嘌呤的有效底物的第一个发现。为了证明甲苯磺酸盐前体的有用性,在本研究中,我们研究了过渡金属催化剂和配体在使用硼酸或格氏试剂作为偶联伙伴来实现交叉偶联反应中。
  • 2-Aminopurine derivatives with C6-substituted olefin as novel cross-linking agents and the synthesis of the corresponding β-phosphoramidite precursors
    作者:Fumi Nagatsugi、Kengo Uemura、Shouji Nakashima、Minoru Maeda、Shigeki Sasaki
    DOI:10.1016/s0040-4020(97)00069-0
    日期:1997.3
    The 6-vinylated 2-aminopurine nucleoside (1), which was prepared by the Pd(0)-catalyzed cross-coupling reaction using guanosine 6-O-tosylate and vinyl-tributylstannane, has been demonstrated as a potential cross-linking agent. However, attempts for its incorporation into oligonucleotides were unsuccessful because of the high reactivity toward nucleophiles. In this study, new 2'-deoxy nucleoside derivatives with 6-(2-substituted vinyl)-2-aminopurine were designed to diminish the reactivity of the vinyl group. These new nucleosides have been shown to maintain reactivity toward potent nucleophiles such as butylamine and thiols, suggesting that they would form cross-linking with the target nucleobase due to the proximity within the sense-antisense duplex. Thus, the corresponding beta-phosphoramidite precursors were successfully prepared, and were applied to an automated oligonucletotide synthesizer. (C) 1997 Elsevier Science Ltd.
