  • Condensation of D-mannosaldehyde derivatives with ethyl diazoacetate. An easy and stereoselective chain elongation methodology for carbohydrates: Application to new syntheses for KDO and 2-deoxy-β-KDO
    作者:Fidel J López-Herrera、Francisco Sarabia-García

    日期:1997.3
    (3R and 3S) beta-Hydroxy-alpha-diazocarbonyl compounds 4(100%, 3:2), 9 (35%, 100:0), 14 (74%, 7:2) and 18 (100%. 100:0), prepared from 2,3,4.5.6-penta-O-acetyl- (3), penta-O-benzyl- (8), 2.3:5,6-di-O-isopropylidene-4-O-(tert-bulyldimethylsilyl)- (13), and 2.3:5,6-di-0-isopropylidene-4-0-acetyl-D-mannosaldehyde (17), respectively, were acetylated, and the resulting beta-ncetoxy-alpha-diazocarbonpl compounds treated with rhodium diacetate to give the corresponding-alpha-enolesters,6 (100%). 11 (35%), 16(100%)and 20 (100%),which are potentially alpha-ketoesiers. Molecularmechanics calculations were used in order to justify the stereoselectivity observed in the initial addition process. The problematic removal of the protecting groups from the alpha-keto esters is discussed. Finally, hydrazinolysis of the cc-enol acetates (to quench the labile resulting a-keto ester as the corresponding and less reactive hydrazines), mild oxidation to the corresponding alpha-diazoesters, deprotection, and final oxidation of the diazo group with m-chloroperhenzoic acid, gave KDO in good yield. Intermediate products were used in the completely stereoselective synthesis of 2-deoxy-beta-KDO, a potent inhibitor for CMP-KDO synthetase. (C) 1997 Published by Elsevier Science Ltd.
    三氢群(3R和3S)的β-羟基-α-重氮甲酰化合物4(100%,3:2)、9(35%,100:0)、14(74%,7:2)和18(100%,100:0),分别由2,3,4,5,6-五-O-乙酰基-(3)、五-O-苄基-(8)、2,3,5,6-二-O-异丙基二酮基-4-O-(叔丁基二甲基硅基)-(13)、以及2,3,5,6-二-O-异丙基二酮基-4-O-乙酰基-D-甘醛(17)制备而成,随后这些化合物被乙酰化。得到的β-乙酰氧基-α-重氮甲酰化合物经二乙酸铑处理,生成相应的α-烯醇酯6(100%)、11(35%)、16(100%)和20(100%),这些化合物可能是α-酮酸酯。为了验证初始加成过程中观察到的立体选择性,进行了分子力学计算。文中讨论了从α-酮酸酯中去除保护基团的难点。最后,通过肼解α-烯醇乙酰酯(以淬灭不稳定的产物α-酮酸酯,生成相应的羟胺,活性较低),进行温和氧化生成对应的α-重氮酸酯,解保护,并最终使用邻氯过苯甲酸氧化重氮基团,成功制得KDO,产量良好。中间产物被用于完全立体选择性合成2-去氧-β-KDO,该化合物是CMP-KDO合成酶的强效抑制剂。 (C)1997 由Elsevier Science Ltd出版。
  • General syntheses of ethyl 2-ulosonates and 3-deoxy-D-manno-oct-2-ulosonic acid from carbohydrate lactones with 1-ethoxyvinyllithium

    日期:1998.5
    Reactions of 1-ethoxyvinyllithium with isopropylidene or benzyl protected sugar lactones afforded the corresponding hemiacetals which, on ozonolysis, gave the ethyl 2-ulosonates. This allowed a rapid and efficient synthesis of 3-deoxy-d-manno-oct-2-ulosonic acid (KDO).
    1-乙氧基乙烯基锂与异亚丙基或苄基保护的糖内酯的反应得到相应的半缩醛,其在臭氧分解中得到2-磺基乙酯。这允许快速且有效地合成3-脱氧-d-甘露糖-辛基-2-磺酸(KDO)。

    日期:1994.9
    β-Acetoxy-α-diazo esters yield α-enol acetate esters quantitatively by reaction with dirhodium tetraacetate. The reaction was used to prepare the major natural compounds 3-Deoxy-D-arabino-2-Heptulosonic acid (DAH, 1) and 3-Deoxy-D-manno-2-Octulosonic acid (KDO, 2) by conversion of the enol acetate function to the corresponding ketone.
