α-Glycosphingolipids via Chelation-Induced Anomerization of O- and S-Glucuronic and Galacturonic Acid Derivatives
摘要:
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.
