  • Diazo Reagents in Copper(I)-Catalyzed Olefination of Aldehydes
    作者:Hélène Lebel、Michaël Davi
    DOI:10.1002/adsc.200800381
    日期:2008.10.6
    The olefination of aldehydes to synthesize unsaturated ketones, esters, amides and phosphonates using diazo reagents and triphenylphosphine in the presence of copper(I) iodide as catalyst, is described. Good to excellent E:Z selectivities as well as yields were obtained for a large variety of aliphatic, aromatic and heteroaromatic aldehydes. The reaction showed also an excellent functional group compatibility
    描述了在碘化铜(I)存在下使用重氮试剂和三苯基膦将醛烯化以合成不饱和酮,酯,酰胺和膦酸酯。对于多种脂族,芳族和杂芳族醛,均获得了良好的E:Z选择性和良好的收率。该反应还显示出优异的官能团相容性,并且在酮,硝基,胺,醚,缩醛,硫醚和卤化物基团的存在下醛被选择性地反应。与先前报道的昂贵的过渡金属络合物相比,使用成本有效的铜盐作为催化剂是有利的。该方法用于scutifoliamide A的全合成,scutifoliamide A是一种具有抗真菌活性的生物活性化合物。
  • P[N(<i>i-</i>Bu)CH<sub>2</sub>CH<sub>2</sub>]<sub>3</sub>N: Nonionic Lewis Base for Promoting the Room-Temperature Synthesis of α,β-Unsaturated Esters, Fluorides, Ketones, and Nitriles Using Wadsworth−Emmons Phosphonates
    作者:Venkat Reddy Chintareddy、Arkady Ellern、John G. Verkade
    DOI:10.1021/jo1012515
    日期:2010.11.5
    serves as an effective promoter for the room-temperature stereoselective synthesis of α,β-unsaturated esters, fluorides, and nitriles from a wide array of aromatic, aliphatic, heterocyclic, and cyclic aldehydes and ketones, using a range of Wadsworth−Emmons (WE) phosphonates. Among the analogues of 1c [R = Me (1a), i-Pr (1b), Bn (1d)], 1a and 1b performed well, although longer reaction times were involved
    双环三氨基膦P(RNCH 2 CH 2)3 N(R = i -Bu,1c)可作为室温下立体选择性合成α,β-不饱和酯,氟化物和腈的有效促进剂芳香族,脂肪族,杂环和环状醛和酮,使用一系列Wadsworth-Emmons(WE)膦酸酯。在1c [R = Me(1a),i -Pr(1b),Bn(1d)]的类似物中,1a和1b表现良好,尽管涉及的反应时间更长,而1d导致的收率低于1c。氰基,氯,溴,甲氧基,氨基,酯和硝基等官能团的耐受性很好。我们能够分离和表征(通过X射线;见上文)由2b和1c形成的反应性WE中间体。
  • A Direct, Copper-Catalyzed Functionalization of Pyridines with Alkynes
    作者:Bruce Arndtsen、Ramsay Beveridge
    DOI:10.1055/s-0029-1218632
    日期:2010.3
    provides a route to access these products directly from terminal alkynes and the parent pyridine, and without prefunctionalization of the pyridine core. In addition, (Z)-alk-2-enylpyridines can be prepared via a related procedure. These reactions are used to synthesize a number of new alkynyl- and alkenyl­-substituted pyridines in one pot. pyridine - copper - catalytic - alkyne - alkene
    提出了一种一锅铜催化的方法来构建2-炔基吡啶。这提供了直接从末端炔烃和母体吡啶获得这些产物的途径,而无需对吡啶核进行预官能化。另外,(Z)-烷-2-烯基吡啶可通过相关方法制备。这些反应用于在一个罐中合成许多新的炔基和烯基取代的吡啶。 吡啶-铜-催化-炔-烯烃
  • Olefination Reactions Using Tetraarylphosphonium (TAP)-Supported Phosphorus Ylides
    作者:Hélène Lebel、André Charette、Michaël Davi、Marie-Noelle Roy、Walid Zeghida
    DOI:10.1055/s-0030-1260065
    日期:2011.7
    Tetraarylphosphonium (TAP)-supported phosphorus ylides were prepared and used in copper-catalyzed olefination reactions with diazo compounds to produce conjugated esters, amides, and phosphonates. The TAP-phosphine oxide can easily be separated from the alkene product, recycled, and reused. alkenes - diazo compounds - green chemistry - Wittig reaction - ylides

  • Solvent-free Wittig olefination with stabilized phosphoranes—scope and limitations
    作者:Thies Thiemann、Masataka Watanabe、Yasuko Tanaka、Shuntaro Mataka
    DOI:10.1039/b311894k
    日期:——
    Neat mixtures of arene/hetarenecarbaldehydes, alkanals as well as alkenals with alkyl (triphenylphosphoranylidene)acetates react exothermally to furnish the corresponding alkenes. In certain cases, heating has to be provided externally. Reaction times are short and yields are generally very high. Neat mixtures of ketones and alkyl (triphenylphosphoranylidene)acetates react preferentially under microwave irradiation. The better stabilized phosphoranes do not react in the solid state with aldehydes or ketones under conventional heating, but necessitate microwave irradiation, although not all of the phosphoranes have been found to be stable under microwave irradiation at 500 W (2450 MHz).
    纯净的芳烃/杂芳烃醛、烷醛以及烯醛与烷基(三苯基磷铵基)醋酸酯发生放热反应,生成相应的烯烃。在某些情况下,需要外部加热。反应时间短,产率通常很高。纯净的酮和烷基(三苯基磷铵基)醋酸酯在微波照射下优先发生反应。稳定性较好的磷烷在固态下与醛或酮在常规加热下不反应,而需要微波照射,尽管并非所有的磷烷在500 W(2450 MHz)的微波照射下都被发现是稳定的。
