  • Synthesis, antimicrobial and cytotoxicity evaluation of new cholesterol congeners
    作者:Mohamed Ramadan El Sayed Aly、Hosam Ali Saad、Shams Hashim Abdel-Hafez
    DOI:10.3762/bjoc.11.208
    日期:——

    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1,2,3-三唑基团,而第三个药效团则是香豆素、疏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。
  • Bimodal Glycosyl Donors Protected by 2-<i>O-</i>(<i>ortho</i>-Tosylamido)benzyl Group
    作者:Feiqing Ding、Akihiro Ishiwata、Yukishige Ito
    DOI:10.1021/acs.orglett.8b01922
    日期:2018.7.20
    A glucosyl donor equipped with C2-o-TsNHbenzyl ether was shown to provide both α- and β-glycosides stereoselectivity, by changing the reaction conditions. Namely, β-glycosides were selectively obtained when the trichloroacetimidate was activated by Tf2NH. On the other hand, activation by TfOH in Et2O provided α-glycosides as major products. This “single donor” approach was employed to assemble naturally
    通过改变反应条件,显示了配备有C 2 -o- TsNH苄基醚的葡糖基供体同时提供α-和β-糖苷的立体选择性。即,当通过Tf 2 NH激活三酰亚胺酸酯时,选择性地获得β-糖苷。另一方面,通过TfOH在Et 2 O中的活化提供了α-糖苷作为主要产物。这种“单一供体”的方法被用来装配自然三糖α-发生d -Glc-(→2 1)-α- d -Glc-(1→6) - d -Glc和它的端基异构体。
  • Stereodivergent Mannosylation Using 2-<i>O</i>-(<i>ortho</i>-Tosylamido)benzyl Group
    作者:Feiqing Ding、Akihiro Ishiwata、Yukishige Ito
    DOI:10.1021/acs.orglett.8b01979
    日期:2018.8.17
    We report a novel strategy for obtaining both anomers from a single mannosyl donor equipped with a C2-o-TsNHbenzyl ether (2-O-TAB) by switching reaction conditions. In particular, the formation of various β-mannosides was achieved with high selectivity by using a mannosyl phosphite in the presence of ZnI2.
    我们报告了一种新颖的策略,可通过切换反应条件,从配备了C2- o- TsNH苄基醚(2- O- TAB)的单个甘露糖基供体获得两种端基异构体。特别地,通过在ZnI 2存在下使用亚甘露糖亚磷酸酯,以高选择性实现了各种β-甘露糖苷的形成。
  • Regioselective Glycosylation of Unprotected Phenyl 1-Thioglycopyranosides with Phenylboronic Acid as a Transient Masking Group
    作者:Thomas Hauch Fenger、Robert Madsen
    DOI:10.1002/ejoc.201300723
    日期:2013.9
    A useful protocol is described for the regioselective glycosylation of the secondary alcohols in unprotected glycosyl acceptors. Phenyl 1-thioglycopyranosides derived from D-glucose, D-galactose, D-glucosamine, L-rhamnose, and L-fucose were treated with phenylboronic acid to install a temporary boronic ester, and then submitted to a Koenigs–Knorr glycosylation with perbenzoylated glucopyranosyl or galactopyranosyl
    描述了一个有用的协议,用于在未保护的糖基受体中对仲醇进行区域选择性糖基化。衍生自 D-葡萄糖D-半乳糖D-葡萄糖胺、L-鼠李糖L-岩藻糖的苯基 1-喃糖苷用苯基硼酸处理以安装临时硼酸酯,然后用过苯甲酰化葡萄糖基进行 Koenigs-Knorr 糖基化或喃半乳糖化物。与葡萄糖苷和半乳糖苷的 3-位偶联获得了良好的产率,但其他受体的产率较低。使用苯基 1-代-β-D-吡喃葡萄糖苷,也可以通过超臂代半乳糖苷供体实现偶联。来自葡萄糖-葡萄糖偶联的产物可以在 6 位进行第二次区域选择性糖基化。在半乳糖系列中,
  • A new method of anomeric protection and activation based on the conversion of glycosyl azides into glycosyl fluorides
    作者:Wolfgang Bröder、Horst Kunz
    DOI:10.1016/0008-6215(93)84071-d
    日期:1993.10
    Glycosyl azides provide reliable anomeric protection stable to conditions for hydrolytic removal of ester groups, for reductive opening or release of acetalic diol protection, for the introduction of ether-type protection, and for glycosylation processes. The utility of this anomeric protection is further enhanced as glycosyl azides may be converted into glycosyl fluorides, which can be activated for
    糖基叠氮化物提供稳定的可靠的端基异构保护,该条件稳定于以下条件:解除去酯基,还原性打开或释放缩醛二醇保护,引入醚型保护以及糖基化过程。由于可将糖基叠氮化物转化为可被糖基化反应活化的糖基化物,因此进一步提高了该端基保护的效用。为此,已经将糖基叠氮化物与乙酰二羧酸二叔丁酯进行了1,3-偶极环加成。用氟化氢-吡啶配合物处理时,N-糖基三唑衍生物直接得到糖基化物。
