    Borylation of Propargylic Substrates by Bimetallic Catalysis. Synthesis of Allenyl, Propargylic, and Butadienyl Bpin Derivatives
    摘要:
    Bimetallic Pd/Cu and Pd/Ag catalytic systems were used for borylation of propargylic alcohol derivatives. The substrate scope includes even terminal alkynes. The reactions proceed stererospecifically with formal S(N)2' pathways to give allenyl boronates. Opening of propargyl epoxides leads to 1,2-diborylated butadienes probably via en allenylboronate intermediate.

  • Synthesis of Benzyl-, Allyl-, and Allenyl-boronates via Copper-Catalyzed Borylation of Alcohols
    作者:Lujia Mao、Kálmán J. Szabó、Todd B. Marder
    DOI:10.1021/acs.orglett.7b00256
    日期:2017.3.3
    Alcohols are among the most abundant and readily available organic feedstocks in industrial processes. The direct catalytic functionalization of sp3 C–O bonds of alcohols remains the main challenge in this field. Here, we report a copper-catalyzed synthesis of benzyl-, allyl-, and allenyl-boronates from benzylic, allylic, and propargylic alcohols, respectively. This protocol exhibits a broad reaction
    酒精是工业过程中最丰富,最容易获得的有机原料之一。醇的sp 3 C–O键的直接催化官能化仍然是该领域的主要挑战。在这里,我们报道了分别由苄基,烯丙基和炔丙基醇的铜催化的苄基,烯丙基和烯丙基硼酸酯的合成。该方案在温和的条件下(包括用于制备仲烯丙基硼酸酯)表现出宽泛的反应范围(40个实例)和高效(高达95%的产率)。初步的机理研究表明,该反应涉及亲核取代。

    secondary and tertiary propargylic alcohols undergo a Meyer–Schuster rearrangement to give enones at room temperature in the presence of a gold(I) catalyst and small quantities of MeOH or 4‐methoxyphenylboronic acid. The syntheses of the enone natural products isoegomaketone and daphenone were achieved using this reaction as the key step. The rearrangement of primary propargylic alcohols can readily be combined
    在室温下,在金(I)催化剂和少量MeOH或4-甲氧基苯基硼酸的存在下,大范围的伯,仲和叔炔丙醇会进行Meyer-Schuster重排,从而得到烯酮。以该反应为关键步骤,实现了烯酮天然产物异麦角酮和达芬酮的合成。伯炔丙醇的重排可以很容易地在单锅法中结合,向所得的末端烯酮中添加亲核试剂,得到β-芳基,β-烷氧基,β-氨基或β-硫代酮。带有相邻的富电子芳基的炔丙醇也可以通过氧,氮和碳亲核试剂进行银催化的醇取代。
  • (<i>Z</i>)-γ-Alkylidenebutenolide Synthesis through Au(I)-Catalyzed 1,3-Acyloxy Migration and the Carbonyl–Ene Reaction
    作者:Pathan Mosim Amin、Qi Cui、Shaozhong Wang、Zhi-Xiang Yu

    1,3-acyloxy migration of propargyl α-ketoesters and a carbonyl-ene cyclization of in situ generated allenyl esters. DFT calculations suggest that the copper salt might play dual roles as both chloride abstractor facilitating the generation of highly active gold catalyst and Lewis acid promoting the stepwise intramolecular carbonyl-ene reaction.
    已经开发了一种双金属协议,以从容易获得的炔丙基 α-酮酯构建 ( Z )-γ-亚烷基丁烯内酯化合物。它涉及金催化的炔丙基α-酮酯的1,3-酰氧基迁移和原位生成的丙二烯酯的羰基-烯环化。DFT 计算表明,铜盐可能起到双重作用,即促进高活性金催化剂生成的氯化物提取剂和促进逐步分子内羰基-烯反应的路易斯酸。
  • A General Procedure for the Synthesis of Enones via Gold-Catalyzed Meyer−Schuster Rearrangement of Propargylic Alcohols at Room Temperature

    Meyer−Schuster rearrangements of propargylic alcohols take place readily at room temperature in toluene with 1−2 mol % PPh3AuNTf2, in the presence of 0.2 equiv of 4-methoxyphenylboronic acid or 1 equiv of methanol. Good to excellent yields of enones can be obtained from secondary and tertiary alcohols, with high selectivity for the E-alkene in most cases. A one-pot procedure for the conversion of primary
    在室温下,在0.2当量的4-甲氧基苯基硼酸或1当量的甲醇存在下,在1-2摩尔%的PPh 3 AuNTf 2的甲苯中,炔丙醇的迈尔-舒斯特重排容易发生。可以从仲和叔醇获得良好至优异的烯酮收率,在大多数情况下,对E-烯烃的选择性高。还开发了一种通过一锅法将伯炔丙醇转化为β-芳基酮的方法,方法是通过Meyer-Schuster重排,然后Pd催化添加硼酸。
  • Neighboring Group Participation of Phosphine Oxide Functionality in the Highly Regio- and Stereoselective Iodohydroxylation of 1,2-Allenylic Diphenyl Phosphine Oxides

    iodohydroxylation of 1,2-allenylic diphenyl phosphine oxides, yielding (E)-2-iodo-3-hydroxy-1-alkenyl diphenyl phosphine oxides with very high stereoselectivity. The scope of this reaction was examined extensively. Notably, studies on the reactivity of optically active substrates indicated that the axial chirality in the starting allenes may be efficiently transferred to the center chirality of the
    建立了两组反应条件,以实现1,2-烯基二苯基膦氧化物的高度区域和立体选择性碘羟基化,从而产生具有非常高的立体选择性的(E)-2-碘-3-羟基-1-烯基二苯基膦氧化物。对该反应的范围进行了广泛的研究。值得注意的是,对旋光性底物的反应性的研究表明,起始丙二烯中的轴向手性可以有效地转移至产物的中心手性,而对映体纯度没有明显的损失。由于含膦化合物作为试剂和配体的重要性,该反应在有机合成中显示出潜力。使用ESI-MS技术对(18)O标记的产品进行研究,该产品是使用(18)O-水作为溶剂制备的,指出(18)O原子与最终产物中的磷结合,并且羟基的氧原子来自于丙二烯反应物的次膦酰基官能团。这些结果为由二苯基次膦酰基的相邻基团的参与形成五元环状中间体提供了有力的证据。据我们所知,这是第一次观察到这种类型的小组的邻近小组参与。
