    名称:
    合成玉米赤霉烯酮内酯的过渡态类似物
    摘要:
    用于玉米赤霉烯酮(1)中内酯官能团水解的催化抗体的开发被认为是解决与雌激素性霉菌毒素相关的动物繁殖力问题的潜在解决方案。提出了磷酰基大环内酯作为用于产生这种抗体的半抗原。经由Mitsunobu反应将适当官能化的芳基膦酸4与外消旋脂族片段5缩合。通过RCM实现大环形成,得到高级中间体23,玉米赤霉烯酮的膦酸酯类似物,准备去保护并缀合到载体蛋白上。

    Substituted 2-aminoalk-3-enoic acid derivative of formula I ##STR1## wherein R.sub.1 is an aliphatic hydrocarbon radical that is substituted by optionally acylated or aliphatically or araliphatically etherified hydroxy, by halogen, by optionally acylated and/or aliphatically substituted amino or by an aza-, diaza-, azoxa- or oxa-cycloaliphatic radical, or is an oxacycloaliphatic hydrocarbon radical bonded via a carbon atom, or is an optionally aliphatically N-substituted or N-acylated azacycloaliphatic hydrocarbon radical, and R.sub.2 is free or esterified carboxy, and their salts exhibit NMDA-antagonistic properties and are useful as active ingredients of anticonvulsive medicaments.

  • Synthetic and computational studies on the tricarboxylate core of 6,7-dideoxysqualestatin H5 involving a carbonyl ylide cycloaddition–rearrangement

    Reaction of diazodiketoesters 17 and 28 with methyl glyoxylate in the presence of catalytic rhodium(II) acetate generates predominantly the 6,8-dioxabicyclo[3.2.1]octanes 29 and 30, respectively. Acid-catalysed rearrangement of the corresponding alcohol 31 favours, at equilibrium, the 2,8-dioxabicyclo[3.2.1]octane skeleton 33 of the squalestatins–zaragozic acids. Force field calculations on the position of the equilibrium gave misleading results. DFT calculations were correct in suggesting that the energy difference between 31 and 33 should be small, but did not always suggest the right major product. Calculation of the NMR spectra of the similar structures could be used to assign the isomers with a high level of confidence.
    二氮二酮酸酯17和28与甲基乙二醛在催化性醋酸(II)的存在下反应,主要生成6,8-二氧双环[3.2.1]辛烷29和30。相应的醇31的酸催化重排在平衡时更倾向于形成鲨烯类和萨拉戈酸的2,8-二氧双环[3.2.1]辛烷骨架33。关于平衡位置的力场计算结果令人误解。密度泛函理论(DFT)计算正确地表明31与33之间的能量差应较小,但并不总是指示出正确的主要产物。对类似结构的核磁共振(NMR)谱的计算可以用来高平地确定异构体。

    Several novel PHA polymer compositions produced using biological systems include monomers such as 3-hydroxybutyrate, 3-hydroxypropionate, 2-hydroxybutyrate, 3-hydroxyvalerate, 4-hydroxybutyrate, 4-hydroxyvalerate and 5-hydroxyvalerate. These PHA compositions can readily be extended to incorporate additional monomers including, for example, 3-hydroxyhexanoate, 4-hydroxyhexanoate, 6-hydroxyhexanoate or other longer chain 3-hydroxyacids containing seven or more carbons. This can be accomplished by taking natural PHA producers and mutating through chemical or transposon mutagenesis to delete or inactivate genes encoding undesirable activities. Alternatively, the strains can be genetically engineered to express only those enzymes required for the production of the desired polymer composition. Methods for genetically engineering PHA producing microbes are widely known in the art (Huisman and Madison, 1998, Microbiology and Molecular Biology Reviews, 63: 21-53). These polymers have a variety of uses in medical, industrial and other commercial areas.
