  • A Versatile Route to 2-Substituted Cyclic 1,3-Dienes via a Copper(I)-Catalyzed Cross-Coupling Reaction of Dienyl Triflates with Grignard Reagents
    作者:A. Sofia E. Karlström、Magnus Rönn、Atli Thorarensen、Jan-E. Bäckvall
    DOI:10.1021/jo971737i
    日期:1998.4.1
    A general synthesis of 2-substituted cyclic 1,3-dienes in two steps from alpha,beta-unsaturated ketones has been developed. Formation of a dien-2-yl triflate followed by a copper(I)-catalyzed cross-coupling reaction with a Grignard reagent gives 2-substituted dienes in fair to excellent yields. Alkyl, aryl, and allyl Grignard reagents can be used.

  • Identification and Synthesis of Branched Wax-type Esters, Novel Surface Lipids from the Spider<i>Argyrodes elevatus</i>(Araneae: Theridiidae)

    presence of unusual esters, new for arthropods. These novel compounds proved to be methyl-branched long-chain fatty acid esters with methyl branches located either close or remote from the internally located ester group. The GC/MS analysis of the prosoma lipid blend from the male cuticle contained one major component, undecyl 2-methyltridecanoate (1). In contrast, four major wax-type esters, 2-methylundecyl
    对来自鳞状寄生寄生蜘蛛Argyrodes elevatus的表皮提取物的分析表明,存在节肢动物新的不寻常的酯。这些新化合物被证明是甲基支链的长链脂肪酸酯,其甲基支链位于内部酯基的附近或远离。雄性表皮中前体脂质混合物的GC / MS分析包含一种主要成分2-甲基十三烷酸十一烷基酯(1)。相反,四种主要的蜡型酯,2,8-二甲基十一酸2-甲基十一烷基酯(2),2,8-二甲基十一酸2,8-二甲基十一烷基酯(3),4-甲基庚酸七癸基酯(4)和14-甲基十七烷基4-酯在雌性prosomata的脂质混合物中鉴定出甲基庚酸甲酯(5)。结构分配基于质谱,气相色谱保留指数和微衍生。所有五种酯的独立合成确保了假定结构的明确证明。优选地,奇数碳链指向不同于普通脂肪酸的独特的生物合成途径,因为在生物合成五种酯中存在的所有酸和醇结构单元期间引入了一个或两个C3起始剂单元。惊人的性二态性与独特的生物合成一起说明了酯在蜘蛛

    Cumulated Ylides XIX.1 Chain-lengthening Difunctionalization of Grignard Compounds by Reaction with Ketenylidenetriphenylphosphorane. A New Route to (E)-α,β- Unsatured Ketones and the Queen Substance2 The reaction of Grignard compounds with ketenylidenetriphenylphosphorane and subsequent hydrolysis yields 2-oxoalkylidenetriphenylphosphoranes. The latter undergo Wittig reaction, whereby (E-α,β-unsaturated ketones are obtained. An application of this strategy to the synthesis of carbonyl homologues of Lepidoptera pheromones and the queen substance is shown.

  • Reinvestigation of the grignard reactions with formic acid. A convenient method for preparation of aldehydes
    作者:Fumie Sato、Kaoru Oguro、Hiroshi Watanabe、Masao Sato
    DOI:10.1016/s0040-4039(00)78630-8
    日期:1980.1
    Grignard reagents react with formic acid in tetrahydrofuran to produce aldehydes in relatively good yields Various aldehydes such as alkyl, aryl, allyl, benzyl and vinyl aldehydes were prepared from the corresponding Grignard reagents. The reaction with vinyl Grignard reagents proceeded with retention of configuration.

  • Addition reactions of organometallic reagents to nitrogen trifluoride and enhanced alkyl–alkyl coupling by NF3
    作者:Randolph K. Belter
    DOI:10.1016/j.jfluchem.2015.03.013
    日期:2015.7
    A survey of the reaction of nitrogen trifluoride (NF3) with various organometallic reagents finds that organomagnesium (Grignard) reagents are the most useful for producing N,N-difluoroaminoalkanes. Alkyl–alkyl coupling is a persistant side reaction. Organolithiums are marginally effective. Organocopper, organozinc reagents undergo primarily alkyl–alkyl coupling catalyzed by the presence of NF3.

    对三氟化氮(NF 3)与各种有机金属试剂的反应进行的调查发现,有机镁(Grignard)试剂对于生产N,N-二氟氨基烷烃最为有用。烷基-烷基偶联是持久的副反应。有机锂微不足道。有机铜有机锌试剂主要通过NF 3的存在进行烷基-烷基偶联反应。有机钙和有机铝试剂没有反应性。
