  • Synthesis of C1-C6 Segment of Carbonolide B: Wolff Rearrangement of Sugar α-Diazo Ketones
    作者:Jayant N. Tilekar、Nitin T. Patil、Dilip D. Dhavale
    DOI:10.1055/s-2000-6343
    日期:——
    Silver benzoate catalysed Wolff rearrangement of a series of α-diazo ketones, derived from furanuronic acids, in methanol proceeds with good yields to produce the corresponding one carbon homologated methyl-5-deoxy-hexo-furanuronate. The utility of methyl-1,2-O-isopropylidene-3-O-methyl-5-deoxy-α-d-xylo-hexo-furanuronate was demonstrated in the synthesis of the right wing segment of carbonolide B - the aglycone of the 16 membered macrolide antibiotic carbomycin B.
    银苯甲酸盐催化的Wolff重排反应在甲醇中对一系列由呋喃糖酸衍生的α-重氮酮进行,获得了良好的产率,生成了相应的一个碳同源物——甲基-5-脱氧-己糖呋喃酸酯。甲基-1,2-O-异丙烯基-3-O-甲基-5-脱氧-α-d-木糖-己糖呋喃酸酯在合成碳醇 B(16个成员的大环抗生素碳霉素 B的苷元)的右侧翼段中的应用得到了验证。
  • Experimental and Computational Investigation of the Uncatalyzed Rearrangement and Elimination Reactions of Isochorismate
    作者:Michael S. DeClue、Kim K. Baldridge、Peter Kast、Donald Hilvert
    DOI:10.1021/ja056714x
    日期:2006.2.1
    isoprephenate by a facile Claisen rearrangement and the other to salicylate via elimination of the enolpyruvyl side chain. Computation suggests that both processes are concerted but asynchronous pericyclic reactions, with considerable C-O cleavage in the transition state but relatively little C-C bond formation (rearrangement) or hydrogen atom transfer to the enolpyruvyl side chain (elimination). Kinetic
    多功能生物合成中间体异分支酸通过两种竞争性途径在水性缓冲液中分解,一种通过简单的克莱森重排导致异戊二酸酯,另一种通过消除烯醇丙酮酸侧链导致水杨酸化。计算表明,这两个过程是协同但异步的周环反应,在过渡态有相当多的 CO 裂解,但相对较少的 CC 键形成(重排)或氢原子转移到烯醇丙酮酰侧链(消除)。动力学实验表明,重排大约比消除有利 8 倍。此外,通过监测 [2-(2)H] 异分支酸的分解来验证 C2 氢原子向 C9 的转移,其由标记的莽草酸化学酶法制备,通过(2)H NMR光谱和观察[3-(2)H]丙酮酸的出现。最后,用 C2 氘代底物获得的同位素效应与假设周环反应机制的计算非常一致。这些结果为异分支酸变位酶和异分支酸丙酮酸裂解酶的机理研究提供了基准,这两种酶分别催化植物和细菌中的重排和消除反应。
  • Biosynthesis of ω-cyclohexyl fatty acids in Alicyclobacillus acidocaldarius: the stereochemistry of the initial 1,4-conjugate elimination
    作者:Sandeep Handa、Heinz G. Floss
    DOI:10.1039/a607122h
    日期:——
    The 1,4-conjugate elimination of H 2 O from shikimic acid 3, the initial step in the biosynthesis of ω-cyclohexyl fatty acids by the bacterium Alicyclobacillus acidocaldarius, has been shown to occur with an overall anti stereochemistry via loss of the pro-6R hydrogen of 3.
    莽草酸 3 是 Alicyclobacillus acidocaldarius 细菌生物合成 Ï-Cyclohexyl 脂肪酸的第一步,其 1,4-conjugate 消去莽草酸 3 中的 H 2 O 是通过失去 3 的原 6R 氢发生的,总体上具有反立体化学性质。
  • Organocatalytic One-Pot Oxidative Cleavage of Terminal Diols to Dehomologated Carboxylic Acids
    作者:Masatoshi Shibuya、Ryu̅suke Doi、Takuro Shibuta、Shun-ichiro Uesugi、Yoshiharu Iwabuchi
    DOI:10.1021/ol3021429
    日期:2012.10.5
    The organocatalytic one-pot oxidative cleavage of terminal 1,2-diols to one-carbon-unit-shorter carboxylic acids is described. The combination of 1-Me-AZADO (cat.), NaOCl (cat.), and NaClO2 caused smooth one-pot oxidative cleavage under mild conditions. A broad range of substrates including carbohydrates and N-protected amino diols were converted without epimerization. Terminal triols and tetraols respectively underwent cleavage of their C-2 and C-3 moieties to afford their corresponding two- and three-carbon-unit-shorter carboxylic acids.
  • Synthesis of novel types of divalent saccharide structures by a ketene acetal Claisen rearrangement
    作者:Barbara Werschkun、Joachim Thiem
    DOI:10.1016/j.tetasy.2004.12.001
    日期:2005.1
    A simple allyl uronate was rearranged to give the branched product, which in turn could be transformed into a spiroannellated bicyclic compound. More complex allyl uronates of D-and L-arabinose were rearranged to give novel methylene-bridged dimeric saccharide structures. (C) 2004 Elsevier Ltd. All rights reserved.
