  • Copper-Catalyzed Borylation of α-Alkoxy Allenes with Bis(pinacolato)diboron: Efficient Synthesis of 2-Boryl 1,3-Butadienes
    作者:Kazuhiko Semba、Tetsuaki Fujihara、Jun Terao、Yasushi Tsuji
    DOI:10.1002/anie.201306843
    日期:2013.11.18
    3‐butadienes with various substitution patterns were formed in good to high yields in a copper‐catalyzed borylation of α‐alkoxy allenes with bis(pinacolato)diboron (see scheme; Bn=benzyl, pin=pinacolate, L is an N‐heterocyclic carbene ligand). The products were found to be useful intermediates for the synthesis of cyclic vinyl boranes, α,β‐unsaturated ketones, and functionalized multisubstituted dienes.
    可依靠的固体:在铜催化的α-烷氧基丙二烯与双(频哪醇)二硼烷的硼化中,以高至高的产率形成了具有各种取代方式的2-苄基1,3-丁二烯(参见图式; Bn =苄基, pin = pinacolate,L为N杂环卡宾配体)。发现该产物是合成环状乙烯基硼烷,α,β-不饱和酮和官能化的多取代二烯的有用中间体。
  • Synthesis of 2-Substituted 2-Amino Ketones by Rhodium-Catalyzed Reaction of<i>N</i>-Sulfonyl-1,2,3-triazoles with 2-Alkenols
    作者:Tomoya Miura、Takamasa Tanaka、Qiang Zhao、Scott G. Stewart、Masahiro Murakami

    日期:2017.2
    A study on a rhodium(II)‐catalyzed reaction of N‐sulfonyl‐1,2,3‐triazoles with 2‐alkenols is reported. The reaction is initiated by insertion of an α‐imino carbene into the O–H linkage of alcohol, forming a 2‐alkenoxy enamide intermediate. A thermal [3,3]‐sigmatropic rearrangement follows to yield 2‐substituted 2‐amino ketone in a stereoselective manner. The successful application of this methodology
    据报道,铑(II)催化N-磺酰基-1,2,3-三唑与2-烯醇的反应。通过将α-亚氨基卡宾插入醇的OH键中,形成2-烯氧基烯酰胺中间体,从而引发反应。随后发生热[3,3]-σ重排,以立体选择性方式产生2-取代的2-氨基酮。还介绍了该方法在(-)- α- conhydrine形式合成中的成功应用。
  • Carbometalation–Carboxylation of 2,3-Allenols with Carbon Dioxide: A Dramatic Effect of Halide Anion

    日期:2013.3.1
    and stereoselective carbomagnesiation of 2,3-allenols with Grignard reagents may smoothly react with carbon dioxide to afford 2(5H)-furanones. A dramatic effect of the halide anion from the Grignard reagent (Br vs Cl) for CO2 activation was observed. The reaction proceeded smoothly under mild conditions to afford the products in 58–93% yields.

  • An Efficient CuCN-Catalyzed Synthesis of Optically Active 2,3-Allenols from Optically Active 1-Substituted 4-Chloro-2-butyn-1-ols
    作者:Jing Li、Wangqing Kong、Chunling Fu、Shengming Ma
    DOI:10.1021/jo900710e
    日期:2009.7.17
    The sequential treatment of optically active terminal propargylic alcohols with n-BuLi/(HCHO)n and regioselective chlorination afforded the corresponding optically active 4-chloro-2-butyn-1-ols. With R1 being a methyl or an ethyl group, an alternative for the synthesis of the corresponding optically active propargylic alcohols is the Novozym 435-catalyzed kinetic resolution of these racemic 4-chloro-2-butyn-1-ols
    用n- BuLi /(HCHO)n连续处理旋光性末端炔丙醇并进行区域选择性氯化,得到相应的旋光性4-氯-2-丁炔-1-醇。当R 1为甲基或乙基时,合成相应的旋光炔丙醇的另一种方法是由Novozym 435催化的这些外消旋4-氯-2-丁炔-1-醇的动力学拆分。这些旋光的4-氯-2-丁炔-1-醇与相应的格氏试剂的随后反应在5 mol%的CuCN的催化下以良好的收率提供了旋光的仲2,3-烯醇,收率高达> 99 %ee。

    作者:Zhan Lu、Shengming Ma
    DOI:10.1002/adsc.200600532
    日期:2007.5.7
    An efficient highly regio- and stereoselective copper(I) chloride-mediated carbometallation of differently substituted 2,3-allenols with primary or secondary alkyl or aromatic Grignard reagents followed by iodination to synthesize fully-substituted allylic alcohols has been developed. This protocol introduces the R4 group from the Grignard reagent to the terminal position of the 2,3-allenols.
