  • Mild Conversion of β-Diketones and β-Ketoesters to Carboxylic Acids
    作者:Yang Zhang、Jingliang Jiao、Robert A. Flowers
    DOI:10.1021/jo0602975
    日期:2006.6.1
    A mild protocol for the conversion of β-ketoesters and β-diketones to carboxylic acids with use of CAN in CH3CN is described. The method is compatible with a number of functional groups, and can generate carboxylic acids under neutral conditions at room temperature. The reaction is fast and general, providing an alternative method to the commonly used malonic ester acid preparation. Initial mechanistic
    描述了在CAN 3 CN中使用CAN将β-酮酸酯和β-二酮转化为羧酸的温和方案。该方法与许多官能团相容,并且可以在室温下在中性条件下生成羧酸。该反应快速且通用,为常用的丙二酸酯制备提供了另一种方法。初步的机理研究表明,β-二羰基烯醇形式的初始氧化可引发反应。硝酸盐作为氧化剂的配体或添加剂的存在对于反应成功至关重要。
  • A study of periselectivity in the thermal cyclisation reactions of diene-conjugated diazo compounds: 1,7-cyclisation as a route to 3H-1,2-diazepines and 1,5-cyclisation leading to new rearrangement reactions of 3H-pyrazoles
    作者:Ian R. Robertson、John T. Sharp
    DOI:10.1016/s0040-4020(01)82434-0
    日期:1984.1
    A range of diene-conjugated diazo compounds has been generated by the thermal decomposition of the sodium salts of the tosylhydrazones of 1-acyl-1, 3-dienes. Those of type (21) with a relationship of the diazo group and the γ, δ-double bond having a hydrogen atom at the diene terminus cyclised only by 1,7 ring closure to give 3-1,2-diazepines (23). This mode of cyclisation was inhibited by the presence
    通过1-酰基-1,3-二烯的甲苯磺酰基hydr的钠盐的热分解,已经产生了一系列二烯共轭的重氮化合物。具有重氮基团和在二烯末端具有氢原子的γ,δ-双键的关系的类型(21)的那些仅通过1,7闭环而环化,得到3 -1,2-二氮杂((23)。这种环化模式被二烯末端甲基或苯基的存在所抑制,例如(45)。这种类型的化合物通过交替的1,5-环闭合而环化,得到3-烯基-3-吡唑类(46)为主要产品。这些观察结果是基于8π电子1,7-电环化反应的螺旋跃迁状态(54)进行解释的。具有γ,δ双键的二烯共轭的重氮化合物,例如(32)也主要通过1,5-电环化而环化,得到3-烯基-3-吡唑,例如(33)。在大多数情况下,在反应条件下3-吡唑重排烯基和氢迁移以产生1-吡唑,例如(34)和(37)。
  • Chemo- and regioselective preparation of zinc enolate from thiol esters by palladium catalyzed cross-coupling reaction
    作者:Ryosuke Haraguchi、Zenichi Ikeda、Akihiro Ooguri、Seijiro Matsubara
    DOI:10.1016/j.tet.2015.08.060
    日期:2015.11
    The palladium catalyzed cross-coupling reaction of thiol esters with bis(iodozincio)methane or 1,1-bis(iodozincio)ethane gave Reformatsky-type enolates. They can react with some electrophiles to give the corresponding adducts and were also trapped by silylation reagents to afford silyl enol ethers. As the method applicable to the thiol ester carrying ketone moiety, it afforded zinc enolates carrying
    钯催化的交叉偶联与二硫醇酯的反应(iodozincio)甲烷或1,1-双(iodozincio)乙烷得到的Reformatsky型烯醇化物。他们可以与一些亲电反应,得到相应的加合物也被困硅烷化试剂,得到烯醇硅醚。作为适用于带有硫醇酯的酮部分的方法,它提供了在同一分子中带有酮的烯醇锌。
  • Rhodium-Catalyzed Regioselective and Chemoselective Deoxygenative Reduction of 1,3-Diketones

    aliphatic carbonyl reduction over aromatic carbonyl reduction. Moreover, the reaction showed good functional group tolerance and broad substrate scope as well as great potential in the late-stage modification and synthesis of natural products and pharmaceutical skeletons. Preliminary mechanistic studies and DFT calculations revealed that this reaction involved the deoxygenation of 1,3-diketone to α, β-unsaturated
    羰基化合物的脱氧还原已得到充分证实。然而,开发的大多数协议通常需要苛刻的反应条件或高反应性/毒性试剂,尽管 1,3-二酮对合成化学和材料科学很重要,但很少探索其脱氧还原。我们在这里描述了在温和反应条件下铑催化的区域选择性和化学选择性脱氧还原 1,3-二酮。与芳香族羰基还原相比,该方法对脂肪族羰基还原表现出异常高的区域选择性。此外,该反应还表现出良好的官能团耐受性和广泛的底物范围,在天然产物和药物骨架的后期修饰和合成中具有巨大潜力。初步机理研究和 DFT 计算表明,该反应涉及 1,3-二酮脱氧为 α, β-不饱和酮及其随后的 1,4-还原。与芳族 C=O 插入相比,脂肪族 C=O 插入 [Rh]-Bpin 的能垒明显较低,这是该还原过程中高区域选择性的原因。
