    摘要:
    合成了柯达他汀AD的二羟基环戊烯酮核心的顺式/反式异构体模型。NMR类比表明,必须对kodaistatin A进行反式配置。关键步骤是添加顺式选择性羟醛。氧化/还原串联提供了β-表异构体抗-羟醛。每个羟醛都被加工成5溴1,4-二酮。后者通过SmI 2介导的羟醛加成而环化。随后的脱水传递了环戊烯酮的动机。

  • Stereochemical assignment of the fungal metabolite xestodecalactone A by total synthesis
    作者:Gerhard Bringmann、Gerhard Lang、Manuela Michel、Markus Heubes
    DOI:10.1016/j.tetlet.2004.02.005
    日期:2004.3
    The first synthesis of the macrocyclic natural product xestodecalactone A, a metabolite of a sponge-derived fungus, is described. By the use of methyl 5-hydroxyhexanoate in its R- or S-configured form, or as its racemate as the precursors, both enantiomers of xestodecalactone A as well as the racemic compound were obtained. Comparison of these synthetic products with the natural product by circular
    描述了大环天​​然产物xestodecalactone A(海绵衍生真菌的代谢产物)的首次合成。通过使用R-或S-构型的形式或作为其外消旋体的5-羟基己酸甲酯作为前体,获得了异十二烷内酯A的对映异构体以及外消旋化合物。这些合成产物与天然产物通过圆二色性(CD)光谱法和通过HPLC在手性相上的比较揭示了天然产物具有(R)-构型。
  • On the selectivity of oxynitrilases towards α-oxygenated aldehydes

    日期:2001.3
    Different α-alkoxy and α,β-di-alkoxy substituted aldehydes have been submitted to the catalytic action of the oxynitrilases from almond (PaHNL) or from Hevea brasiliensis (HbHNL), in order to explore the possibility of using these enzymes for the preparation of complex cyanohydrins. The selectivity of both enzymes towards these compounds was found to be largely dependent on the substitutents, being
    不同α -烷氧基和α,β二-烷氧基取代的醛已经被提交到醇腈的从杏仁催化作用(PaHNL)或者从巴西橡胶树(HbHNL),为了探索使用这些酶制剂的可能性复杂的氰醇。发现两种酶对这些化合物的选择性在很大程度上取决于取代基,因为醛带有在空间上更需要的苯基取代基的醛较低。违背化学添加HCN,它总是与用于形成的轻微偏爱发生的反非对映体,所述酶cyanuration存在与面部偏好,硅或再根据所使用的生物催化剂,得到氰醇的混合物,取决于起始的对映异构醛,该混合物可以富含顺式非对映异构体。

  • Enantioselective sensing of insect pheromones in water
    作者:Briana L. Hickey、Junyi Chen、Yunfan Zou、Adam D. Gill、Wenwan Zhong、Jocelyn G. Millar、Richard J. Hooley
    DOI:10.1039/d1cc05540b
    日期:——
    cavitands and cationic dyes has been shown to optically sense insect pheromones at micromolar concentration in water. Machine learning approaches were used to optimize the most effective array components, which allows differentiation between small structural differences in targets, including between different diastereomers, even though the pheromones have no innate chromophore. When combined with chiral additives
    水溶性深空腔和阳离子染料的阵列组合已被证明可以在水中以微摩尔浓度光学感知昆虫信息素。机器学习方法用于优化最有效的阵列组件,即使信息素没有先天发色团,也可以区分目标的微小结构差异,包括不同的非对映异构体之间的差异。当与手性添加剂结合使用时,对映体区分是可能的,这取决于信息素的大小和形状。
