Stereoselective Synthesis of Neu5Acα(2→5)Neu5Gc: The Building Block of Oligo/Poly(→5-OglycolylNeu5Gcα2→) Chains in Sea Urchin Egg Cell Surface Glycoprotein
摘要:
The synthesis of a sialic acid dimer derivative, Neu5Acalpha(2-->5)Neu5Gc, is described. The synthetic strategy is based on the use of allyl alcohol to achieve an exclusive alpha-sialylation product. The allyloxy group is also a latent glycolic acid that provides the subsequent coupling with neuraminate with minimal protection-deprotection manipulations.
