    Ugi反应在一锅法合成尿嘧啶多恶菌素C类似物中的应用
    摘要:
    描述了使用Ugi反应简单,两步合成尿嘧啶多氧合酶C(UPOC)甲酯的酰胺衍生物的方法。Ugi反应中使用的四个组分是2',3'-异丙基吡啶保护的尿苷5'-醛,2,4-二甲氧基苄胺,异恶唑羧酸和可转换的异腈N-(2-{[(叔丁基二甲基甲硅烷基)氧基]甲基}苯基)腈。在Ugi反应之后,用HCl在MeOH中的溶液处理可实现异亚丙基和N-苄基的脱保护,并将异腈衍生的酰胺(Ugi产物)转化为相应的甲酯。该程序适用于与多恶英和尼克霉素核苷肽抗生素相关的新型化合物的自动多平行合成。

    Stereoselective Synthesis of Novel Uracil Polyoxin C Conjugates as Substrate Analogues of Chitin Synthase
    摘要:
    Stereoselective syntheses of both the natural (C5'-S) and unnatural (C5'-R) diastereoisomers of uracil polyoxin C methyl ester have been developed. The key stereocontrolled step involves nucleophilic addition of trimethylsilyl cyanide to the appropriate chiral sulfinimine derived from 2',3'-protected 5'-formyluridine and (S)-(-)-tert-butanesulfinamide or (R)-(+)-tert-butanesulfinamide, respectively. A variety of substrate mimics designed to function as inhibitors of chitin synthase have been synthesized by conjugation of the methyl ester of uracil polyoxin C (UPOC) with activated isoxazole carboxylic acids. Amide bond formation was accomplished via coupling of the amino functionality of UPOC methyl ester with a free isoxazole acid using HBTU or alternatively an isoxazole pentafluorophenyl ester. The substrate mimics incorporate features of the nucleoside-peptide antibiotics, the polyoxins and the nikkomycins, as well as features of the transition state structure expected during polymerization of the natural chitin synthase substrate uridine diphosphoryl-N-acetylglucosamine (UDP-GlcNAc), namely, a metal-binding site and glycosyl oxocarbenium ion mimic.
