  • Cross-benzoin and Stetter-type reactions mediated by KOtBu-DMF via an electron-transfer process

    the occurrence of different ionic pathways have been evaluated to elucidate the mechanism of a model cross-benzoin-like reaction along with a radical route initiated by an electron-transfer process to benzil from the carbamoyl anion derived from DMF. This mechanistic investigation has culminated in a different proposal, supported by calculations and a trapping experiment, based on double electron-transfer
    在催化(25 mol%)KO t存在下,在DMF中芳族α-二酮(苯)与芳族醛(苯偶姻型反应)和查耳酮(Stetter型反应)的缩合卜被报道。两种类型的物质转运过程均具有良好的效率和完全的化学选择性。根据可能的中间体的光谱证据(质谱分析)和文献报道,对不同离子途径的发生进行了评估,以阐明模型交叉安息香样反应的机理以及由电子转移引发的自由基途径得自DMF的氨基甲酰基阴离子制取苯甲醚的方法。这项机理研究最终提出了另一种方案,该方案得到了计算和捕集实验的支持,该方案基于双电子转移至苯并形成相应的烯二醇阴离子作为关键的反应性中间体。KO t Bu-DMF和KO t中苯甲酸酯活化方式的机理比较还描述了Bu-DMSO系统。

    A convenient heterogeneous continuous-flow procedure for the polarity reversal of aromatic α-diketones is presented. Propaedeutic batch experiments have been initially performed to select the optimal supported base capable to initiate the two electron-transfer process from the carbamoyl anion of the N,N-dimethylformamide (DMF) solvent to the α-diketone and generate the corresponding enediolate active species. After having identified the 2-tert-butylimino-2-diethylamino-1,3-dimethylperhydro-1,3,2-diazaphosphorine on polystyrene (PS-BEMP) as the suitable base, packed-bed microreactors (pressure-resistant stainless-steel columns) have been fabricated and operated to accomplish the chemoselective synthesis of aroylated α-hydroxy ketones and 2-benzoyl-1,4-diones (benzoin- and Stetter-like products, respectively) with a good level of efficiency and with a long-term stability of the packing material (up to five days).

    提出了一种方便的异质连续流程,用于芳香族α-二酮的极性反转。首先进行了初步的批量实验,以选择能够从N,N-二甲基甲酰胺(DMF)溶剂的碳酰胺负离子向α-二酮发起两电子转移过程并生成相应的烯二醇酸活性物种的最佳支持碱。在确定了聚苯乙烯(PS-BEMP)上的2-tert-丁基亚胺-2-二乙基氨基-1,3-二甲基过氧化-1,3,2-二氮磷烷作为合适的碱后,制备并操作了填充床微反应器(耐压不锈钢柱),以实现芳基化α-羟基酮和2-苯甲酰-1,4-二酮(苯甲酮和Stetter样品,分别)的化学选择性合成,效率较高,并且填料材料的长期稳定性(长达五天)。

  • Methylsulfinyl (Dimsyl) Anion as Umpolung Catalyst for the Chemoselective Cross-Benzoin Reaction of α-Diketones with Aldehydes
    作者:Olga Bortolini、Giancarlo Fantin、Valeria Ferretti、Marco Fogagnolo、Pier Paolo Giovannini、Alessandro Massi、Salvatore Pacifico、Daniele Ragno

    日期:2013.11.11
    AbstractThe hitherto unreported ability of the methylsulfinyl carbanion (dimsyl anion) to generate acyl anion equivalents is described. The dimsyl anion, in fact, efficiently catalyzes chemoselective intermolecular cross‐benzoin condensations of diaryl α‐diketones (benzils) with various aromatic and aliphatic aldehydes to give the corresponding aryl‐aryl and aryl‐alkyl benzoin benzoates in an atom‐economic fashion. The dimsyl anion acts as an environmentally friendly alternative to the toxic cyanide anion and it is obtained by in situ deprotonation of dimethyl sulfoxide (DMSO) solvent with a catalytic amount of a strong base, potassium tert‐butoxide (t‐BuOK) the optimal promoter. The assumption that the methylsulfinyl carbanion is the active catalyst in the title transformation is supported by electrospray ionization mass spectrometry (ESI‐MS) experiments.magnified image
  • Syntheses of 2-Alkylthio-(4,5-Diaryl)imidazoles
    作者:Mona Salimi、Mohsen Amini、Abbas Shafiee
    DOI:10.1080/104265090884265
    日期:2005.7.1
    A series of 2-alkylthio-4,5-diarylimidazoles were synthesized in three steps. The reaction of ammonium thiocyanate with benzoylbenzoins 4 gave 4,5-diarylimidazole-2-thiones 5. Alkylation of compound 5 with alkyl iodide yielded 2-alkylthio-4,5-diarylimidazoles 6. Chlorosulfonation of compound 6 followed by ammonia gave the desired compounds 4-[2-alkylthio-4(5)-(4-substituted phenyl)imidazole-5(4)-yl]benzensulfonamides 7.
