  • Deoxygenation of Polyhydroxybenzenes:  An Alternative Strategy for the Benzene-Free Synthesis of Aromatic Chemicals
    作者:Chad A. Hansen、J. W. Frost
    DOI:10.1021/ja0176346
    日期:2002.5.1
    e requires 2 enzyme-catalyzed and 2 chemical steps. By contrast, synthesis of hydroquinone using the shikimate pathway and intermediacy of quinic acid requires 18 enzyme-catalyzed steps and 1 chemical step. Methylation of triacetic acid lactone, cyclization, and regioselective deoxygenation of phloroglucinol methyl ether affords resorcinol. Given the ability to synthesize triacetic acid lactone from
    在葡萄糖和芳香族化学品(如连苯三酚、对苯二酚和间苯二酚)之间建立了新的合成联系。这种方法的核心是从 1,2,3,4-四羟基苯、羟基氢醌和间苯三酚甲基醚中去除一个氧原子,分别形成连苯三酚、氢醌和间苯二酚。脱氧是通过起始多羟基苯的 Rh 催化氢化,然后是推定的二氢中间体的酸催化脱水来完成的。连苯三酚合成包括将葡萄糖转化为肌醇,氧化为肌 2-肌糖,脱水为 1,2,3,4-四羟基苯,以及脱氧形成连苯三酚。通过 myo-2-inosose 合成连苯三酚需要 4 个酶催化和 2 个化学步骤。为了比较,通过没食子酸中间体和莽草酸途径从葡萄糖合成连苯三酚需要至少 20 个酶催化步骤。一种新的对苯二酚的无苯合成采用将葡萄糖转化为 2-脱氧青蟹肌糖,将该肌糖脱水为羟基氢醌,然后脱氧形成对苯二酚。通过 2-脱氧青蟹肌糖合成氢醌需要 2 个酶催化和 2 个化学步骤。相比之下,使用莽草酸途径和奎尼酸中间体合成对苯二酚需要

    For the synthesis of dicarba-β-d-isomaltose derivatives, the carbaglucosyl triflate locked in 4C1 conformation was synthesized by protecting with butane-2,3-diacetal group or benzylidene group. Then, 5a,5a'-dicarba-β-d-maltose and 5a,5a'-dicarba-α,β-d-trehalose were synthesized by the SN2-type inversion reaction using 4,6-O-benzylidene carbaglucosyl triflate with 4-OH and 1-OH carba-β-d-glucose derivatives
    设计了新颖的碳水化合物模拟物,其包含两个5a-carba-d-葡萄糖残基,每个残基在还原和非还原端,因此这些模拟物是5a,5a'-dicarba-d-葡萄糖生物酶。双碳二糖具有吸引人的特征,例如对内源性降解酶的稳定性,并且对糖基化反应(如美拉德反应)具有抵抗力。对于二氨基甲酸酯-β-d-异麦芽糖衍生物的合成,通过用2,3-丁烷或亚苄基保护,合成了锁定在4C1构象中的氨基甲酸氨基葡萄糖。然后,使用4,6-O-亚苄基氨基葡萄糖葡萄糖基三氟甲磺酸酯通过SN2-型转化反应合成5a,5a'-dicarba-β-d-麦芽糖和5a,5a'-dicarba-α,β-d-海藻糖。 -OH和1-OH氨基-β-d-葡萄糖衍生物,以及类似的5a,5a'

    converts ubiquitous d-glucose 6-phosphate (G-6-P) into the specific carbocycle, 2-deoxy-scyllo-inosose with an aid of NAD(+)-NADH recycling. The NAD(+)-dependent first step of the DOIS reaction was examined in detail by the use of 6-phosphonate and 6-homophosphonate analogs of G-6-P. Both analogs showed competitive inhibition against the DOIS reaction with K(i) values of 1.3 and 2.8 mM, respectively, due to
    生物合成临床上重要的氨基环醇抗生素的关键酶是2-脱氧-鞘氨醇合酶(DOIS),该酶将无处不在的d-葡萄糖6-磷酸酯(G-6-P)转化为特定的碳环2-脱氧-鞘氨醇NAD(+)-NADH回收的帮助下的肌苷。通过使用G-6-P的6-膦酸酯和6-均膦酸酯类似物详细检查了DOIS反应的NAD(+)依赖性第一步。两种类似物均显示出对DOIS反应的竞争性抑制作用,其K(i)值分别为1.3和2.8 mM,这是由于它们无法随后消除磷酸盐。基于分光光度法直接观察到氢化物从6膦酸酯转移至NAD(+)形成的NADH,

    (+)-proto-Quercitol (1) and (-)-vibo-quercitol (2), both of which could be readily prepared by the bioconversion of myo-inositol, were successfully converted into the corresponding 4-methylenecyclohex-5-ene-1,2,3-triol derivatives. These compounds were demonstrated to be suitable precursors, preserving their configurations, for bioactive carba-aminosugars such as the potent chemical chaperone drug candidates, N-octyl-4-epi-beta-valienamine (NOEV, 3) and N-octyl-beta-valienamine (NOV, 4).
