  Facile synthesis of three bidesmosidic oleanolic acid saponins with strong inhibitory activity on pancreatic lipase

  摘要：

  The first synthesis of scabiosaponins E (1), F (2), and G (3), three new oleanolic acid saponins with strong inhibitory activity on pancreatic lipase isolated from the Chinese traditional medicinal herb Scabiosa tschiliensis, was efficiently achieved in an one-pot strategy under the combined use of glycosyl trichloro-acetimidates and p-toluene 1-thioglycosides (STol) as donors.

  Synthesis of a-O- and a-S-Glycosphingolipids Related to Sphingomonous cell Wall Antigens Using Anomerisation

  摘要：

  来自Spingomonadacaece的糖脂类类似物，具有O-、S-和SO2-连接，通过TiCl4催化的螯合诱导的异构化进行了制备。其中包括具有O-和S-糖苷键的中间体异构化的例子，以及β-硫葡萄糖醇酸（β-糖苷硫醇）的异构化。β-O-葡萄糖醛酸酯和β-O-半乳糖醛酸酯的前体采用苯甲酰化三氯乙酰胺高效制备。β-糖苷硫醇是β-S-衍生物的前体。含有三唑的天然糖脂类模仿物使用CuI催化的叠氮烷炔环加成反应在THF中制备。当前正在评估这些糖脂抗原对iNKT细胞的影响。

• α-Glycosphingolipids via Chelation-Induced Anomerization of <i>O</i>- and <i>S</i>-Glucuronic and Galacturonic Acid Derivatives
  作者：Wayne Pilgrim、Paul V. Murphy

  DOI：10.1021/ol802915h

  日期：2009.2.19

  Bacterial glycolipids containing either alpha-glucuronic acid or alpha-galacturonic acid residues have an important role in the innate-type immune response to Gram-negative bacteria. Synthesis of closely related compounds, including a novel alpha-SO2 glycolipid mimetic, is described from carbohydrate precursors where anomerization is a key step. Very high stereoselectivites (>97:3 in favor of alpha) were observed from O-glycoside precursors.
