Chemical Synthesis of a Glycolipid Library by a Solid-Phase Strategy Allows Elucidation of the Structural Specificity of Immunostimulation by Rhamnolipids
variations in the carbohydrate part, the lipid components, and the stereochemistry of the 3-hydroxy fattyacids was designed and synthesized. The enantioselective synthesis of the 3-hydroxy fattyacid building blocks was achieved by employing asymmetric hydrogenation of 3-oxo fattyacids. Glycolipids were prepared by this approach without any intermediary isolation steps, mostly in excellent yields. Final
