    摘要:
    季碳的拥挤性质阻碍了它们的制备,尤其是在需要立体控制时。在这里,我们报告了一种用于创建具有广泛底物范围的季碳中心的生物催化方法,导致具有这种结构特征的不同化合物类别。关键步骤包括由来自大肠杆菌的金属依赖性 3-甲基-2-氧代丁酸羟甲基转移酶 (KPHMT) 及其变体催化,将 3,3-二取代的 2-含氧酸醛醇加成到醛上。由此产生的 3,3,3-三取代的 2-含氧酸被转化为 2-氧代内酯和 3-羟基酸,并直接转化为 ulosonic 酸衍生物,所有这些衍生物都带有嵴二烷基、嵴环烷基和螺环季铵中心。此外,这些反应中的一些使用来自外消旋亲核试剂的单一对映异构体来提供立体纯的季碳。

    Treatment of the crude ether-insoluble resin glycoside (convolvulin) from seeds of Pharbitis nil (Pharbitis Semen), called pharbitin, with indium(III) chloride in methanol provided seven oligoglycosides of hydroxy fatty acid methyl esters partially acylated by 2-methyl-3-hydroxybutyric (nilic) and 2S-methylbutyric acids. Their structures were elucidated on the basis of NMR and MS data and chemical

These compounds (1–11) were considered to be generated via methyl esterification of the carboxyl group in acylated glycosidic acids. Their structures including stereochemistry were elucidated on the basis of a combination of the spectroscopic and chemical

    A new, highly modified fatty acid amide, varitatin A (1), was isolated from the fungus Penicillium variabile HXQ-H-1 cultivated with the DNA methyltransferase inhibitor 5-azacytidine. The structure including the absolute configuration of 1 was established by analysis of NMR and MS data, together with chemical degradation and Mosher's method based on MPA esters. Compound 1 showed cytotoxicity against HCT-116 cells with an IC50 value of 2.8 mu M and also inhibited the effects of protein tyrosine kinases.
  • Absolute Configuration of Scyphostatin
    作者:Shoichi Saito、Natsuki Tanaka、Katsumi Fujimoto、Hiroshi Kogen
    DOI:10.1021/ol991351p
    日期:2000.2.1
    [GRAPHICS]The absolute configuration of the side chain of scyphostatin (1) has been established. The chemical degradation of 1 gave 4 and 9, which correspond to the C7'-C12' and C13'-C16' fragments of the natural products, respectively. The spectroscopic data and [alpha](D) values of both compounds were compared to those of authentic samples. The results show that the absolute configuration of 1 is 8'R,10'S,14'R.
