    A new synthesis for the 2-deoxy KDO 2 by aldolic condensation of 2,3:5,6-di-O-isopropylidene-4-acetyl-D-manno aldehyde 4 with ethyl diazoacetate and conversion of the condensation product to the 3-deoxy-2-diazo ester 13 in four steps is reported. Rhodium (II) decomposition of the diazo compound leads to the α-anomer of the 2-deoxy pyranose 14 stereospecifically. Removla of isopropylidene groups and
    2,3:5,6-二-O-异亚丙基-4-乙酰基-D-甘露糖醛4与重氮乙酸乙酯的醛基缩合合成2-脱氧KDO 2的新方法,并将缩合产物转化为3-报道了四个步骤中的脱氧-2-重氮酯13。重氮化合物的铑(II)分解导致2-脱氧吡喃糖14的α-异构体立体定向。除去异亚丙基和酯水解可提供2,这是CMP-KDO合成酶的有效抑制剂。
  • 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

    (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。

    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.
