    名称:
    Carbonylation of Alkynyl Epoxides:  Synthesis of 5-Hydroxy-2,3-dienoate Esters and 2,3-Dihydrofuran-3-ol Derivatives
    摘要:
    The carbonylation of alkynyl oxiranes catalyzed by (MePh2)(4)Pd in the presence of 20 atm of carbon monoxide in methanol gives methyl 5-hydroxy-2,3-pentadienoates in good yields. When the reaction is performed on alkynyl oxiranemethanol derivatives, 4,5-dihydrofuran-3-ol derivatives are obtained stereoselectively. These products arise from the spontaneous cyclization of a dihydroxyallenyl ester intermediate.

    末端炔丙基醇与蒽的金催化胺化反应,对C(1)-加成和1,2-碳迁移具有非典型的化学选择性
    摘要:
    这项工作报道了末端炔丙基醇与蒽或异恶唑的金催化的胺化反应,可产生具有完全化学选择性的E构型的α-氨基-2-en-1和1 al。与典型的C(2)路线相反,这些催化亚胺仅在末端炔烃上与C(1)亲核加成一起发生。对于3,3-二烷基丙-1-炔-3-醇,甲基取代基优于长烷基链,这是1,2-向α-亚氨基金卡宾的迁移基团。对于仲丙-1-炔-3-醇,苯基,乙烯基和环丙基取代基作为迁移基团优于氢,从而避免了典型的金卡宾反应。进行了DFT计算以合理化所观察到的C(1)-区域选择性和基于金卡宾途径的优选环丙基迁移。

  • Simultaneous Synthesis of Both Rings of Chromenes via a Benzannulation/<i>o</i>-Quinone Methide Formation/Electrocyclization Cascade
    作者:Nilanjana Majumdar、Keith A. Korthals、William D. Wulff
    DOI:10.1021/ja210655g
    日期:2012.1.18
    A new route to the chromene ring system has been developed which involves the reaction of an α,β-unsaturated Fischer carbene complex of chromium with a propargyl ether bearing an alkenyl group on the propargylic carbon. This transformation involves a cascade of reactions that begins with a benzannulation reaction and is followed by the formation of an o-quinone methide, and finally results in the emergence
    开发了一种色烯环体系的新路线,该路线涉及铬的α,β-不饱和费歇尔卡宾络合物与在炔丙碳上带有烯基的炔丙醚的反应。这种转化涉及一系列反应,从苯并环化反应开始,然后形成邻醌甲基化物,最后在电环化时产生色烯。通过使用芳基卡宾络合物,该反应被扩展以提供通路。这是色烯的首次合成,其中色烯系统的两个环均在一步中生成,并在 lapachenole 和维生素 E 的合成中得到突出体现。
  • Ruthenium-catalyzed formation of pyrazoles or 3-hydroxynitriles from propargyl alcohols and hydrazines
    作者:Julia Kaufmann、Elisabeth Jäckel、Edgar Haak
    DOI:10.24820/ark.5550190.p010.893
    日期:——
    Functionalized pyrazoles are generated from secondary propragyl alcohols and hydrazines in a rutheniumcatalyzed cascade process, consisting of redox isomerization, Michael addition, cyclocondensation and dehydrogenation steps. The same bifunctional catalyst mediates the conversion of tertiary propargyl alcohols with hydrazine to 3-hydroxynitriles via anti-Markovnikov hydroamination followed by elimination

    日期:1982.1
    The reactions of various alkenynols with phenylsulfenyl chloride result in the formation of either vinylallene sulfoxides or vnylacetylene sulfoxides, depending on the substitution pattern of the starting material.

    作者:Jiaqiong Sun、Guangfan Zheng、Qiao Zhang、Yimin Wang、Shengbiao Yang、Qian Zhang、Yan Li、Qian Zhang
    DOI:10.1021/acs.orglett.7b01599
    日期:2017.7.21
    The first copper-catalyzed imidovinylation of alkynes has been developed, which grants facile access to various (E)-2-imido-2,4-dienals with high stereoselectivity under mild conditions. This transformation also represents the first 1,3-carbon migration of propargylic alcohols and their derivatives.
