  • Copper-Catalyzed Nitrogen Loss of Sulfonylhydrazones: A Reductive Strategy for the Synthesis of Sulfones from Carbonyl Compounds
    作者:Xing-Wen Feng、Jian Wang、Ji Zhang、Jing Yang、Na Wang、Xiao-Qi Yu
    DOI:10.1021/ol101955x
    日期:2010.10.1
    An efficient method for the synthesis of sulfones via nitrogen loss of sulfonyl hydrazones is described. The reaction was performed in the presence of simple copper salt and base by utilization of sulfonyl hydrazones, which were easily prepared from carbonyl compounds. A wide variety of aryl and alkyl sulfones were obtained in moderate to good yields.

  • Novel Model Sulfur Compounds as Mechanistic Probes for Enzymatic and Biomimetic Oxidations
    作者:Alicia B. Peñéñory、Juan E. Argüello、Marcelo Puiatti
    DOI:10.1002/ejoc.200400382
    日期:2005.1
    is proposed that the mechanism of the biomimetic sulfoxidations of sulfides 1c and 2−5 by TPPFeIIICl is direct oxygen transfer. Three enzymes − Coprinus cinereus peroxidase (CiP), horseradish peroxidase (HRP) and chloroperoxidase (CPO) − were studied in the oxidation of sulfides 1a, 2, 4 and 5. The use of a racemic alkyl hydroperoxide in the CiP enzymatic oxidation of sulfides 5 and 2 yielded the corresponding
    为了测试硫化物自由基阳离子在仿生和酶促氧化中的中介作用,硫化物 PhSCH3 (1a)、PhSCH2Ph (1b)、PhSCHPh2 (1c)、PhSCPh3 (1d)、CH3SCHPh2 (2)、PhSCH2CH=CH2 (3)、PhSCH2CH =CHPh (4) 和 CH3SCH2CH=CHPh (5) 进行了研究,并将它们的结果与相应的化学电子转移 (CET) 和光致电子转移 (PET) 氧化所获得的结果进行了比较。在硝酸铈 (IV) 铵 (CAN) 存在下,CET 从 3-5 生成的自由基阳离子仅产生烷基阳离子和硫基自由基 (RS·) 的裂解产物,而 2·+ 提供了裂解产物,主要是 α -去质子化产品。硫化物 1a 和 1b 用 C(NO2)4 光化学处理只得到相应的亚砜,而裂解是 1c、2 和 5 光反应的主要途径,对于 1d,仅观察到后一个过程。这些结果支持我们选择硫化物 RSCHPh2、RSCH2CH=CHPh
  • An efficient approach for the synthesis of novel methyl sulfones in acetic acid medium and evaluation of antimicrobial activity
    作者:Gollapudi RAVI KUMAR、Chandra Rao DASIREDDY、Ravi VARALA、Vijay KOTRA、Hari Babu BOLLIKOLLA

    日期:——

    A series of nine methyl sulphones (3a–3i) starting from the aldehydes (1a–1i) were synthesized in two consecutive steps. In the first step, preparation of allyl alcohols (2a–2i) from their corresponding aldehydes by the reaction of sodium borohydride in methanol at room temperature is reported. Finally, methyl sulphones are synthesized by condensing sodium methyl sulfinates with allyl alcohols in the presence of BF3.Et2O in acetic acid medium at room temperature for about 2–3 h. The reaction conditions are simple, yields are high (85%–95%), and the products were obtained with good purity. All the synthesized compounds were characterized by their 1H, 13C NMR, and mass spectral analysis. All the title compounds were screened for antimicrobial activity. Among the compounds tested, the compound 3f has inhibited both Gram positive and Gram negative bacteria effectively and compound 3i has shown potent antifungal activity. These promising components may help to develop more potent drugs in the near future for the treatment of bacterial and fungal infections.

    以醛(1a-1i)为起点,通过两个连续步骤合成了一系列九种甲基砜(3a-3i)。第一步,在室温下通过硼氢化钠在甲醇中的反应从相应的醛制备烯丙基醇(2a-2i)。最后,在醋酸介质中,BF3.Et2O 存在下,室温下冷凝甲基亚磺酸钠与烯丙基醇,约 2-3 小时,合成甲基砜。反应条件简单,收率高(85%-95%),产物纯度好。所有合成化合物均通过 1H、13C NMR 和质谱分析进行了表征。对所有标题化合物进行了抗菌活性筛选。在测试的化合物中,化合物 3f 对革兰氏阳性菌和革兰氏阴性菌都有有效的抑制作用,而化合物 3i 则显示出强大的抗真菌活性。这些有前景的成分可能有助于在不久的将来开发出更多治疗细菌和真菌感染的特效药物。
  • Iron(III) Chloride‐Catalyzed Direct Sulfonylation of Alcohols with Sodium Arenesulfinates
    作者:M. Amarnath Reddy、P. Surendra Reddy、B. Sreedhar
    DOI:10.1002/adsc.200900905
    日期:2010.10.9
    A new protocol for the direct sulfonylation of benzylic, allylic and homoallylic alcohols with sodium arenesulfinates is described by using iron(III) chloride as a catalyst and chlorotrimethylsilane as an additive. This method requires no preactivation of alcohols. Surprisingly in the reaction with homoallyl alcohols nucleophilic addition of sulfinate anion, occurs at the terminal double bond instead
    通过使用氯化铁(III)作为催化剂和氯三甲基硅烷作为添加剂,描述了一种新的方案,用于将苄基,烯丙基和均烯丙基醇与芳烃亚磺酸钠直接磺酰化。该方法不需要酒精的预活化。令人惊讶地,在与均烯丙基醇的反应中,亚磺酸根阴离子的亲核加成发生在末端双键处,而不是在醇上进行亲核取代。
  • Atropisomerism of 1-alkylcyclohepta [b]pyrrol-2(1H)-ones. Isolation of the rotational isomers of 1-(2,4-dimethyl-3-pentyl)cyclohepta [b]pyrrol-2(1H)-one
    作者:Yukari Ikeda、Nobuo Kato、Akira Mori、Hitoshi Takeshita
    DOI:10.1002/mrc.1260300604
    日期:1992.6
    1-Alkylcyclohepta[b]pyrrol-2(1H)-ones showed rotational isomerism around the CN bond. Two rotamers of the 1-(2,4-dimethyl-3-pentyl) derivative were isolable by high-performance liquid chromatography at 0°C. The activation free energy, measured by the line-shape analysis of the variable-temperature NMR spectra, was 86.8 kJ mol−1 at 25°C. In a bromo derivative, a positive buttressing effect was observed.
