  • N-Trichloroethoxycarbonyl-glucosamine derivatives as glycosyl donors
    作者:Wulf Dullenkopf、Julio C. Castro-Palomino、Leonardo Manzoni、Richard R. Schmidt

    -D-glucopyranosyl trichloroacetimidate (6). Reaction of 5 with five selectively protected glycosides as glycosyl acceptors in the presence of N-iodosuccinimide/trifluoromethanesulfonic acid as the promoter system furnished the corresponding beta-glycosides in good yields, thus exhibiting the valuable glycosyl donor properties of 5. Reductive removal of the trichloroethoxycarbonyl (Teoc) group afforded the corresponding
    D-葡萄糖胺可以容易地转化为1,3,4,6-四-O-乙酰基-2-脱氧-2-(2,2,2-三氯乙氧基羰基氨基++)-D-吡喃葡萄糖(2)。从该中间体可以得到有价值的糖基供体。在三氟化硼醚化物存在下与乙硫醇反应得到乙基3,4,6-三-O-乙酰基-2-脱氧-1-硫-2-(2,2,2-三氯乙氧基羰基氨基)-β-D-吡喃葡萄糖苷( 4),经N-乙酰化得到N-乙酰基-N-三氯乙氧基羰基衍生物(5)。在2中选择性除去1-O-乙酰基,然后在碱存在下用三氯乙腈处理,得到3,4,6-三-O-乙酰基-2-脱氧-2-(2,2,2-三氯乙氧基羰基氨基) -α-D-吡喃葡萄糖基三氯乙酰亚胺酸酯(6)。在N-碘代琥珀酰亚胺/三氟甲磺酸作为促进剂体系存在下,5与5个被选择性保护的糖苷作为糖基受体的反应以良好的产率提供了相应的β-糖苷,因此显示出5的有价值的糖基供体性质。 (Teoc)基团以高收率提供了相应的N-乙酰基保护
  • Synthesis, antimicrobial and cytotoxicity evaluation of new cholesterol congeners

    3β-Azidocholest-5-ene (3) and (3β)-3-(prop-2-yn-1-yloxy)cholest-5-ene (10) were prepared as substrates to synthesize a variety of three-motif pharmacophoric conjugates through CuAAC. Basically, these conjugates included cholesterol and 1,2,3-triazole moieties, while the third, the pharmacophore, was either a chalcone, a lipophilic residue or a carbohydrate tag. These compounds were successfully prepared in good yields and characterized by NMR, MS and IR spectroscopic techniques. Chalcone conjugate 6c showed the best antimicrobial activity, while the lactoside conjugate 27 showed the best cytotoxic effect in vitro.

    3β-氮杂胆甾-5-烯(3)和(3β)-3-(丙-2-炔-1-氧基)胆甾-5-烯(10)被制备为底物,以合成各种三基团药效团结合物通过CuAAC。基本上,这些结合物包括胆固醇和1,2,3-三唑基团,而第三个药效团则是香豆素、疏水残基或碳水化合物标记中的一个。这些化合物以良好的产率成功制备,并通过NMR、MS和IR光谱技术进行表征。香豆素结合物6c显示出最佳的抗微生物活性,而乳糖苷结合物27在体外显示出最佳的细胞毒作用。

    N,N-Diacetylimido protection of 2-aminoglycosides is an elegant strategy but has had limited applications due to unexpected side reactions in glycosylation. We found that high acid concentrations could diminish the side reactions. We observed intermolecular hydrogen bonding among alcohols and acids could disrupt. Assuming that intermolecular hydrogen bonding accelerates the formation of 1,2-orthoamides
    2-氨基糖苷的N , N-二乙酰亚氨基保护是一种优雅的策略,但由于糖基化中的意外副反应而应用有限。我们发现高酸浓度可以减少副反应。我们观察到醇和酸之间的分子间氢键可能会破坏。假设分子间氢键加速了 1,2-邻酰胺的形成并且破坏分子间氢键可以转变为所需的糖基化,我们成功地在范围广泛的醇受体的糖基化中以及在一个一锅合成受保护的人乳寡糖,乳-N-新四糖。

    Three regioisomers of lactose fatty acid monoesters at positions 3', 6' and 3 and other related compounds have been chemically synthesized. The 3'- and 6'-O-palmitoyl-D-lactose derivatives were prepared via the regioselective esterification at O-3' and O-6' of the dibutylstannylene derivatives obtained from benzyl 2,3,6-tri-O-benzyl-4-O-(2,6-di-Obenzyl-β-D-galactopyranosyl)-β-D-glucopyranoside (1)
