    基于过渡金属氧化物的磁性核壳纳米粒子选择性氧化葡萄糖
    摘要:
    研究了基于阳离子过渡金属(Cu 和 Co)的核壳(核:磁铁矿,壳:SiO2、ZrO 或 CeO)磁性纳米颗粒在 β-葡萄糖选择性氧化为葡萄糖酸 (GLU) 和葡萄糖醛酸 (GLUU) 酸中的作用,工作温度为低温,以 H2O 作为氧化剂,且液相中不存在任何碱。通过 FTIR、XRD、NH- 和 CO-TPD 以及 TGA-DTA 分析对催化剂进行了表征。在最佳反应条件(40℃、10 h)下,β-葡萄糖的最高转化率为86.2%,GLU和GLUU的选择性分别为33.8%和14.6%。这些结果与 MSA@Co(分别为:M – 磁铁矿;S – 二氧化硅壳,A – APTES)催化剂相对应。这种催化剂可以通过简单的外部磁铁轻松回收,并可重复使用多次连续运行,而催化效率不会发生任何变化。

    Processes are disclosed for the synthesis of 2-substituted furan derivatives from a substrate having a carbonyl functional group (C=O), with hydroxy-substituted carbon atoms at alpha and beta positions, relative to the carbonyl functional group. In one embodiment, an alpha-, beta-dihydroxy carboxylate is dehydrated to form a dicarbonyl intermediate by transformation of the alpha-hydroxy group to a second carbonyl group and removal of the beta-hydroxy group. The dicarbonyl intermediate undergoes cyclization and dehydration to produce the 2-substituted furan derivative. Optionally, a further step of oxidation may be carried out, for example to convert a hydroxymethyl group, as a 5-substituted furan ring, to a carboxy group of 2,5-furan dicarboxylic acid.

    Processes are disclosed for the synthesis of a cracked product from a starting substrate having a carbonyl functional group (C=O), with hydroxy-substituted carbon atoms at alpha and beta positions, relative to the carbonyl functional group. In one embodiment, an alpha-, beta-dihydroxy carboxylic acid or carboxylate is dehydrated to form a dicarbonyl intermediate by transformation of the alpha-hydroxy group to a second carbonyl group and removal of the beta-hydroxy group. The dicarbonyl intermediate is cracked to form the cracked product in which the first and second carbonyl groups are preserved. Either or both of (i) the cracked product and (ii) a second cracked product generated from cleavage of a carbon-carbon bond of the dicarbonyl intermediate, may be hydrogenated to form additional products.

    Processes are disclosed for synthesizing an α-amino acid or α-amino acid derivative, from a starting compound having a carbonyl functional group (C=O), with hydroxy-substituted carbon atoms at alpha (α) and beta (β) positions, relative to the carbonyl functional group. An α-, β-dihydroxy carboxylic acid or carboxylate is dehydrated to form a dicarbonyl intermediate by transformation of the α-hydroxy group to a second carbonyl group (adjacent a carbonyl group of the starting compound) and removal of the β-hydroxy group. This dicarbonyl intermediate is optionally cracked to form a second dicarbonyl intermediate having fewer carbon atoms but preserving the first and second carbonyl groups. Either or both of the dicarbonyl intermediate and the cracked dicarbonyl intermediate are then reductively aminated.
