    摘要:
    高氯二氮杂嗪,一种具有优异稳定性的基本中性的有机盐,已被发现非常适用于游离的以及部分保护的糖,酚,硫酚,硫醇和其他醇以及胺的乙酰化。高氯酸二氮杂pin鎓催化的乙酰化反应温和,无有机和无溶剂,并且不影响底物上存在的对酸敏感的保护基团,例如TBDMS / TBDPS / Tr醚和异亚丙基/亚苄基乙缩醛。在部分受保护的碳水化合物衍生物/多羟基化合物中进行区域选择性羟基保护是可行的,并被证明是常规合成此类化合物的一种省时的简便方法。容易制备催化剂,温和的反应条件和对环境有益的方案是该反应的显着特征。苯酚和苯硫酚的乙酰化反应所获得的结果可以通过DFT计算获得的局部亲核指数来合理化。

    The glucosylation of some coumarin and flavone derivatives on incubation with the hairy roots of morning glory (Pharbitis nil) was previously reported. We further studied the biotransformation of benzaldehyde- and acetophenone-type derivatives. Vanillin and isovanillin were reduced to alcoholic derivatives and glucosylated at the phenolic and the alcoholic hydroxyl groups. In the case of 3,4-dihydroxybenzaldehyde, the formyl group was reduced and the 3-hydroxyl or 4-hydroxyl groups were glucosylated to give monoglucosides. The 3-hydroxyl group was predominantly glucosylated to the 4-hydroxyl group. 4-β-D-Glucopyranosyloxy-3-methoxybenzylalcohol was obtained in low yield. In time-course experiments with vanillin, it was found that the high-level reduction of the formyl group and glucosylation of the phenolic hydroxyl group occurred, and finally 4-O-β-D-glucopyranosylvanillylalcohol was obtained as the main product. In the case of 3,4-dimethoxybenzaldehyde, 3,4,5-trimethoxybenzaldehyde, and salicylaldehyde, the formyl groups were reduced, and then the hydroxyl groups at the benyl position were glucosylated to give alcoholic glucosides in relatively high yields. In 4-hydroxy-3-methoxyacetophenone, the 4-hydroxyl group was glucosylated and two dimerized glucosides, biphenyl and biphenylether types, were obtained in low yields. In acetophenone, 1-β-D-glucopyranosyloxy-1-phenylethane and 2-β-D-glucopyranosyloxyacetophenone were obtained. As mentioned above P. nil hairy roots showed various biotransformative activities including glucosylation of phenolic and benzylic hydroxyl groups, reduction of the formyl group near the benzene ring, and phenol oxidation dimerization. The glucosylation reaction was especially interesting for the production of valuable glucosides.
    之前已有研究报告显示,某些香豆素黄酮生物在与牵牛花毛根(Pharbitis nil)孵育时发生了葡萄糖化反应。我们进一步研究了苯甲醛乙酰苯酮类生物生物转化。香草醛和异香草醛被还原为醇类生物,并分别在羟基和醇羟基上发生了葡萄糖化。在3,4-二羟基苯甲醛的情况下,甲醛基被还原,而3-羟基或4-羟基则被葡萄糖化,从而生成单糖苷。3-羟基主要葡萄糖化为4-羟基。4-β-D-葡萄糖喃酯氧基-3-甲氧基苄醇的产率较低。在与香草醛的时间过程实验中,发现甲醛基的高平还原和羟基的葡萄糖化同时发生,最终获得了4-O-β-D-葡萄糖喃醇香草醇作为主要产物。在3,4-二甲氧基苯甲醛3,4,5-三甲氧基苯甲醛水杨醛的情况下,甲醛基被还原后,苄位的羟基被葡萄糖化,生成的醇类葡萄糖苷的产率相对较高。在4-羟基-3-甲氧基乙酰苯酮中,4-羟基被葡萄糖化,并生成了两种二聚葡萄糖苷,即联苯联苯醚类,产率较低。在乙酰苯酮中,得到1-β-D-葡萄糖喃酯氧基-1-苯乙烯和2-β-D-葡萄糖喃酯氧基乙酰苯酮。如上所述,P. nil毛根显示了多种生物转化活性,包括羟基和苄羟基的葡萄糖化、苯环附近甲醛基的还原以及氧化二聚化。葡萄糖化反应尤其值得关注,因为它能够产生有价值的葡萄糖苷。

  • Molecular Interactions between Barley and Oat β-Glucans and Phenolic Derivatives

    Equilibrium dialysis, molecular modeling, and multivariate data analysis were used to investigate the nature of the molecular interactions between 21 vanillin-inspired phenolic derivatives, 4 bile salts, and 2 commercially available beta-glucan preparations, Glucagel and PromOat, from barley and oats. The two beta-glucan products showed very similar binding properties. It was demonstrated that the two beta-glucan products are able to absorb most phenolic derivatives at a level corresponding to the absorption of bile salts. Glucosides of the phenolic compounds showed poor or no absorption. The four phenolic derivatives that showed strongest retention in the dialysis assay shared the presence of a hydroxyl group in para-position to a CHO group. However, other compounds with the same structural feature but possessing a different set of additional functional groups showed less retention. Principal component analysis (PCA) and partial least-squares regression (PLS) calculations using a multitude of diverse descriptors related to electronic, geometrical, constitutional, hybrid, and topological features of the phenolic compounds showed a marked distinction between aglycon, glucosides, and bile salt retention. These analyses did not offer additional information with respect to the mode of interaction of the individual phenolics with the beta-glucans. When the barley beta-glucan was subjected to enzyme degradation, the ability to bind some but not all of the phenolic derivatives was lost. It is concluded that the binding must be dependent on multiple characteristics that are not captured by a single molecular descriptor.
