    摘要:
    通过使用迭代计算机技术,已完全像ABC系统一样分析了一系列1,2-二取代3,3-二甲基丁烷的100 MHz光谱。已显示化学位移与从具有类似取向的取代基的系统预测的那些相当合理地吻合。的笨拙(Ĵ克)和反式(Ĵ吨偶合常数)被证明是对相同的符号且符号相反的Ĵ宝石。邻位偶合常数的值及其对浓度变化的相对不敏感性表明,这些化合物主要以单一构象体的形式存在。带有薄纱状的1,2-取代基。两者都不J g或J t与取代基的电负性或大小相关。因此,在这一系列化合物中这些参数中观察到的细微差异可能反映了构象异构体的不同相对种群。

  • Screening method for the evaluation of asymmetric catalysts for the reduction of aliphatic ketones

    ATH reductions of aliphatic ketones in water catalyzed by ruthenium coordinated by prolinamide ligands produce alcohols with moderate enantiomeric excesses in most cases. A set of seven aliphatic ketones is proposed for a rapid evaluation of the enantioselectivity of catalysts by one-pot multi-substrates reduction. The screening of a library of prolinamides shows that according to the structure of

    申请人:Winchell S. Harry
    公开号:US20050112066A1
    公开(公告)日:2005-05-26
    Cyclic polyaza chelators that possess high affinity and specificity for first transition series metal cations exhibit an unanticipated improvement in biological activity when administered as complexes with cations of the alkaline earth metals, Ca(II) and Mg(II), most notably Ca(II). By virtue of this improvement, these complexes are particularly effective in the treatment of pathological conditions, including ischemia and ischemia-reperfusion injury.

  • Neuroprotection and cardioprotection afforded by chelators with high affinity and specificity for cations of first transition series elements
    申请人:CONCAT, LTD. a California Limited Partnership
    公开号:US20040006055A1
    公开(公告)日:2004-01-08
    Compounds that demonstrate chelation affinity and selectivity for first transition series elements are administered to patients suffering from such conditions as ischemia, prolonged seizures and trauma to provide neuroprotection, cardioprotection, or both. These compounds when administered form complexes with chelatable iron and copper cations and thereby mitigate the ability of these cations to catalyze Haber-Weiss reactions that form toxic hydroxy free radicals that cause tissue injury. These compounds also form complexes with chelatable zinc cations thereby inhibiting the cytotoxicity associated with excess chelatable zinc.

  • Synthesis of perhydrofuro [2,3-b] furan compounds and the structure-activity relationships of the antifeeding active compounds.
    作者:Yasuhiro KOJIMA、Natsuki KATO
    DOI:10.1271/bbb1961.44.855
    日期:——
    A new synthetic route to perhydrofuro [2, 3-b] furan was developed by employing 3-sub-stituted furan derivatives (t-butyl and phenyl systems) that were derived by coupling reaction with epoxides and a new reagent, lithium di (3-furyl) cuprate. The synthesized furo-furan compounds were prepared to various derivatives for testing antifeeding activities. The results suggest that higher degree activities depend on the presence of a moderately polar, substituent group. Moreover, in order to enhance the antifeeding activities, the hydroxy group of the hem iacetal should be protected with an acyl or methyl group.
    通过与环氧化物和一种新试剂--二(3-呋喃基)铜酸锂--进行偶联反应,利用 3-亚取代的呋喃衍生物(叔丁基和苯基体系),开发出了一条全氢呋喃 [2, 3-b] 的新合成路线。合成的呋喃化合物被制备成各种衍生物,用于测试其抗侵染活性。结果表明,较高的活性取决于中等极性取代基的存在。此外,为了提高抗飞播活性,半缩醛的羟基应使用酰基或甲基进行保护。
