  • O-Isopropylidenation of carbohydrates catalyzed by vanadyl triflate
    作者:Chun-Cheng Lin、Mi-Dan Jan、Shiue-Shien Weng、Chang-Ching Lin、Chien-Tien Chen
    DOI:10.1016/j.carres.2006.04.001
    日期:2006.8
    Vanadyl triflate has been identified as a mild and efficient catalyst for the chemoselective O-isopropylidenation of functionalized carbohydrates with acetone and acetone equivalents. The current protocol is compatible with a diverse array of protecting groups and the products can be readily isolated by simple aqueous wash. (c) 2006 Elsevier Ltd. All rights reserved.
  • Syntheses of a series of lacto-N-neotetraose clusters using a carbosilane dendrimer scaffold

    4-Pentenyl (2,3,4,6-tetra-O-acetyl-beta-(D)-galactopyranosyl)-(1 -> 4)-(3,6-di-O-acetyl-2-deoxy-2-phthalimido-beta-(D)-glucopyranosyl)-( 1 -> 3)-(2,6-di-O-benzoyl-beta-(D)-gatactopyranosyl)-(1 -> 4)-2,3,6-tri-O-benzoyl-beta-(D)-glucopyranoside (4) was synthesized by regio-selective glycosylation of 4-pentenyl (2,6,-di-O-benzoyl-beta-(D)-galactopyranosyl)-(1 -> 4)-2,3,6-tri-O-benzoyl-beta-(D)-glueopyranoside and (2,3,4,6-tetra-O-acetyl-beta-(D)-galactopyranosyl)-(1 -> 4)-3,6-di-O-acetyl-2-deoxy-2-phthalimido-beta-(D)-glucopyranosyl chloride. By conversion of the protecting groups followed by thioacetylation, 4 was transformed into the corresponding lacto-N-neotetraose derivative, 5-(acetylthio)pentenyl (2,3,4,6-tetra-O-acetyl-beta-(D)-galactopyranosyl)-(1 -> 4)-O-(3,6-di-O-acetyl-2-acetamido-2-deoxy-beta-(D)-glucopyranosyl)-(1 -> 3)-(2,4,6-di-O-acetyl-beta-(D)-galactopyranosyl)-(1 -> 4)-2,3,6-tri-O-acetyl-beta-(D)-glucopyranoside (6). The lacto-N-neotetraose derivative 6 was introduced into carbosilane dendrimer cores of three shapes, and three kinds of new carbosilane dendrimers peripherally functionalized by lacto-N-neotetraose were obtained.

  • New Applications of the <i>n</i>-Pentenyl Glycoside Method in the Synthesis and Immunoconjugation of Fucosyl GM<sub>1</sub>:  A Highly Tumor-Specific Antigen Associated with Small Cell Lung Carcinoma
    作者:Jennifer R. Allen、Samuel J. Danishefsky
    DOI:10.1021/ja992594f
    日期:1999.12.1
    to allow for smooth global deprotection. The synthesis and subsequent immunocharacterization served to confirm the assigned structure of the natural tumor antigen. Fully synthetic conjugate 1c advances our program toward the goal of using a synthetic vaccine containing fucosyl GM1 as a potential target for immune attack against small cell lung carcinoma.
    岩藻糖基 GM1 戊烯糖苷 1b 的合成及其与载体蛋白 KLH 的结合产生 1c 是相关的。使用包含在还原端正戊烯基糖苷 (NPG) 中的侧链烯烃实现 1b 的生物偶联。努力的关键步骤是使用我们的磺酰胺糖苷化方案进行立体特异性 [3 + 3] 偶联反应(参见 23 + 12 → 15)。需要预先安装 NPG 以获得最佳 [3 + 3] 耦合产量并允许平滑的全局脱保护。合成和随后的免疫表征用于确认天然肿瘤抗原的指定结构。完全合成的偶联物 1c 使我们的计划朝着使用含有岩藻糖基 GM1 的合成疫苗作为免疫攻击小细胞肺癌的潜在目标的目标前进。
