  • Isoquinoline-1-Carboxylate as a Traceless Leaving Group for Chelation-Assisted Glycosylation under Mild and Neutral Reaction Conditions

    Glycosyl isoquinoline‐1‐carboxylate was developed as a novel benchtop stable and readily available glycosyl donor. The glycosylation reaction was promoted by the inexpensive Cu(OTf)2 salt under mild reaction conditions. The copper isoquinoline‐1‐carboxylate salt was precipitated from the solution and thus rendered a traceless leaving group. Surprisingly, the proton from the acceptor was absorbed by
    糖基异喹啉-1-羧酸被开发为一种新型的台式稳定且易于获得的糖基供体。在温和的反应条件下,廉价的Cu(OTf)2盐促进了糖基化反应。异喹啉-1-羧酸盐从溶液中沉淀出来,因此成为无痕的离去基团。令人惊讶地,来自受体的质子被沉淀的属络合物吸收,并且反应混合物保持在中性pH。还证明了促进的糖基化与促进的糖基化完全正交,并且在温和的反应条件下,可以从台式稳定的异头酯结构单元迭代合成寡糖

    intermediates for the synthesis of carbohydrates. The addition of the triphenyl phosphite ligand shuts down the isomerization pathway and promotes the allylic etherification pathway. The addition of diphenyl phosphate improved the diastereoselectivity for the addition reaction. Interestingly, opposite diastereoselectivity was observed for sterically demanding alcohol nucleophiles compared to less sterically
    我们最近为Achmatowicz重排产物开发了一种新型的Ir催化的动态动力学异构化反应。在此更新中,我们表明,在适当的配体和添加剂存在下,源自Achmatowicz重排的产物也可以进行Ir催化的动态动力学烯丙基醚化反应,从而提供用于合成碳水化合物的有用中间体。亚磷酸三苯酯配体的添加关闭了异构化途径并促进了烯丙基醚化途径。磷酸二苯酯的加入改善了加成反应的非对映选择性。有趣的是,与对空间要求较低的醇亲核试剂相比,对空间要求较高的醇亲核试剂观察到相反的非对映选择性。该方法还适用于几种2的合成

  • DISAL glycosyl donors for efficient glycosylations under acidic conditions: Application to solid-phase oligosaccharide synthesis
    作者:Lars Petersen、Knud J. Jensen
    DOI:10.1039/b105872j
    日期:——
    The use of DISAL (methyl dinitrosalicylate) glycosyl donors in efficient Lewis acid-promoted glycosylations is reported. N-Acetyl-D-glucosamine monosaccharide acceptors are successfully glycosylated at O-6 or O-4 using benzyl- and benzoyl-protected DISAL donors in CH2Cl2 or nitromethane in the presence of LiClO4. The resultant disaccharides are isolated in yields ranging from 35 to 93%. Other Lewis acids such as FeCl3, TMSOTf, or BF3·Et2O also prove efficient for glycosylation of the secondary alcohol cyclohexanol. However, for the synthesis of disaccharides, the mild activation by LiClO4 gives higher yields. This approach is extended to efficient solid-phase glycosylation of a D-glucosamine derivative anchored by the 2-amino group through a Backbone Amide Linker (BAL) to a polystyrene support.
    报告了在高效的路易斯酸促进糖基化反应中使用 DISAL(二硝基水杨酸甲酯)糖基供体的情况。在 CH2Cl2硝基甲烷中,在 LiClO4 的存在下,使用苄基和苯甲酰基保护的 DISAL 给体成功地在 O-6 或 O-4 处糖基化了 N-乙酰基-D-氨基葡萄糖单糖受体。由此分离出的二糖收率在 35% 到 93% 之间。其他路易斯酸(如 FeCl3、TMSOTf 或 BF3-Et2O)也被证明能有效地对仲醇环己醇进行糖基化。不过,在合成二糖时,LiClO4 的温和活化可获得更高的产量。这种方法扩展到了通过骨架酰胺连接物(BAL)将 2-基锚定在聚苯乙烯支架上的 D-氨基葡萄糖生物的高效固相糖基化。
  • Why Are the Hydroxy Groups of Partially Protected <i>N</i>-Acetylglucosamine Derivatives Such Poor Glycosyl Acceptors, and What Can Be Done about It? A Comparative Study of the Reactivity of <i>N</i>-Acetyl-, <i>N</i>-Phthalimido-, and 2-Azido-2-deoxy-glucosamine Derivatives in Glycosylation. 2-Picolinyl Ethers as Reactivity-Enhancing Replacements for Benzyl Ethers
    作者:David Crich、Vadim Dudkin
    DOI:10.1021/ja010086b
    日期:2001.7.1
    Competition experiments were used to determine that the 4-OH of a 2-deoxy-2-azidoglucose derivative is more reactive than that of the corresponding N-phthalimido glucose derivative which, in turn, is more easily glycosylated than the N-acetyl derivative. Glycosylation of the C-OH groups of the N,N-diacetyl and N-acetyl-N-benzyl glucosamine was also found to be superior to that of the simple N-acetyl substance. The 3-O-picolinyl ether of a 4,6-O-benzylidene-protected N-acetylglucosamine was shown to have a strong intramolecular hydrogen bond to the adjacent acetamide group. This interaction does not persist in the 3-O-picolinyl-6-O-benzyl N-acetylglucosamine derivative. owing to a probable competing hydrogen bond between the 4-OH and the picolinyl ether. However, in the 3-O-picolinyl-4-O-benzyl N-acetylglucosamine regioisomer the picolinyl-acetamide hydrogen bond persists and leads to an enhancement of reactivity of the 6-OH, over and above that in the corresponding 3-O-benzyl ether. due to disruption of the typical intermolecular amide hydrogen bonding scheme. It is demonstrated that the picolinyl ether is readily removed by hydrogenolysis at atmospheric pressure and room temperature.
