  • The invention of radical reactions. Part XXXVIII. Homologation of car☐ylic acids with acrylamide and synthetic studies of 3-deoxy-D-arabino-2-heptulosonic acid (DAH) and its 4-epimer
    作者:Derek H.R. Barton、Wansheng Liu

    日期:1997.8
    Alkyl radicals generated from O-acyl derivatives of N-hydroxy-2-thiopyridone added onto acrylamide at room temperature to form crystalline 2-(2-pyridylsulfanyl)-car☐amides. Desulfurization of the latter by nickel boride at room temperature afforded primary amides in quantitative yield. 3-Deoxy-D-arabino-2-heptulosonic acid (DAH), its 4-epimer, and their derivatives were effectively synthesized from
    由N-羟基-2-硫代吡啶酮的O-酰基衍生物产生的烷基在室温下加到丙烯酰胺上,形成结晶的2-(2-吡啶基硫烷基)-car☐酰胺。在室温下通过硼化镍将后者脱硫,以定量收率得到伯酰胺。通过类似的自由基化学方法,从商业D-核糖内酯有效合成了3-Deoxy-D-阿拉伯糖-2-庚基磺酸(DAH),其4-表位及其衍生物。

  • A new and concise synthesis of 3-deoxy-D-arabino-2-heptulopyranosonic acid (DAH) and derivatives through the radical chemistry of Barton esters
    作者:Derek H.R. Barton、Wansheng Liu
    DOI:10.1016/s0040-4039(96)02331-3
    日期:1997.1
    Barton ester-based radical chemistry was applied in the synthesis of 3-deoxy-D-orobino-2-heptulopyranosonic acid (DAH) from commercial D-ribonolactone, The radical reaction with olefin 2, followed by aqueous work-up, provided the seven-carbon sugar compounds 5 and 6 (3:1) in 60% yield. Removal of the isopropylidene groups from 5 and hydrolysis of the ethyl ester yielded the DAH barium salt quantitatively. Copyright (C) 1996 Elsevier Science Ltd

    different stabilized diazo compounds is reported. Studies on the reactivity of the condensation products have been undertaken, finding out novel transfromations of β-oxy-α-diazo carbonyl compounds with sinthetic applications. Thus, a stereoselective Wolff rearrangement provided syn 2-hydroxy-1-methyl compounds, which represent macrolide type structural subunits. On the other hand, rhodium (II) mediated rearrangements
