    Fritsch–Buttenberg–Wiechell重排的修饰:一条通往不对称丁二炔的简便途径
    摘要:
    Fritsch–Buttenberg–Wiechell重排的一种修饰已用于从1,1-二溴烯烃前体形成不对称取代的1,3-丁二炔。反应通过锂-卤素交换进行,然后芳基或炔基部分迁移以提供丁二炔骨架。由市售的芳基醛或羧酸氯化物分三步轻松形成二溴代烯烃,使该方法成为传统丁二炔合成方法的有吸引力的替代方法。

    Cascade and Effective Syntheses of Functionalized Tellurophenes
    摘要:
    A one-pot and transition-metal-catalyst-free synthetic strategy to construct functionalized tellurophenes has been developed. Substituted 1,1-dibromo-l-en-3-ynes are smoothly converted to tellurophenes with telluride salts in high yield via a series of cascade reactions through reductive debromination, hydrotelluration, nucleophilic cyclization, and aromatization. Close inspection of the results clearly showed that the reactivity of in situ prepared telluride salts are significantly influenced by the polarity of the solvent system and the electronic nature of the substituent on the enyne substrate. This method reports the first direct synthesis of 3-aryltellurophenes in high yields at room temperature. This novel reaction strategy is also found to be a promising synthetic method for multisubstituted tellurophenes and selenophenes.

  • Enantioselective Organocatalytic Michael Addition to Unsaturated Indolyl Ketones
    作者:Dmitri Trubitsõn、Jevgenija Martõnova、Marina Kudrjašova、Kristin Erkman、Ivar Järving、Tõnis Kanger

    An efficient enantioselective organocatalytic method for the synthesis of N-alkylated indoles with α-branched alkyl substituents from the corresponding unsaturated indolyl ketones via a Michael addition has been developed. The resulting products were obtained in high enantioselectivities and in good yields. Various nucleophiles (nitroalkanes, malononitrile, malonic esters) can be used. The substitution
    已经开发了一种有效的对映选择性有机催化方法,其通过迈克尔加成反应由相应的不饱和吲哚合成具有α-支链烷基取代基的N-烷基化的吲哚。得到的产物具有高对映选择性和良好的产率。可以使用各种亲核试剂(硝基烷,丙二腈丙二酸)。吲哚环的取代方式对反应结果没有显着影响。在杂芳族环的任何位置上的吸电子和供电子取代基均具有良好的耐受性。
  • Synthesis of Unsymmetrically Substituted 1,3-Butadiynes and 1,3,5-Hexatriynes via Alkylidene Carbenoid Rearrangements

    日期:2003.2.1
    Unsymmetrically substituted 1,3-butadiynes and 1,3,5-hexatriynes are synthesized in four steps from commercially available aldehydes or carboxylic acids. The key step in this process involves a Fritsch-Buttenberg-Wiechell rearrangement, in which an alkylidene carbenoid intermediate subsequently rearranges to the desired polyyne. This rearrangement proceeds under mild conditions, and it is tolerant
    不对称取代的1,3-丁二炔和1,3,5-己三炔由市售的醛或羧酸分四个步骤合成。该过程中的关键步骤涉及Fritsch-Buttenberg-Wiechell重排,其中亚烷基类胡萝卜素中间体随后重排为所需的多炔。这种重排在温和的条件下进行,并且可以耐受一系列功能。通常,在程序上容易形成二烃前体,再加上重排步骤的有效性,使得该方法成为利用催化的传统的二炔和三炔合成方法的有吸引力的替代方法。

    Bestmann–Ohira reagent. The reaction offers a convenient route for the synthesis of regioisomerically pure 3,5-disubstituted or 3,4,5-trisubstituted pyrazoles in excellent yields. However, di-ynones and molecules possessing both ynone and enone functionalities provide only monocycloaddition products, whereas another multiple bond undergoes Michael addition with the methoxide anion.
    目前的工作探索了迄今尚未发现的与Bestmann–Ohira试剂成对的双极性亲和性炔的反应性。该反应提供了以优异的产率合成区域异构纯的3,5-二取代的或3,4,5-三取代的吡唑的简便途径。然而,二炔和同时具有炔官能团的分子仅提供单环加成产物,而另一个多重键与甲醇根阴离子进行迈克尔加成。

    A one-pot tandem Diels–Alder/Nazarov reaction of 1-aryl-3-(trimethylsilyl) ynones has been achieved to generate carbo- and heterocyclic fused ring systems in good to excellent yields. The β-silyl effect is instrumental in accessing this otherwise challenging cascade annulation reaction. The tandem reaction proceeds in the presence of BCl3 to generate three new carbon–carbon bonds, a quaternary carbon
