Neoglycopeptide Synthesis by Suzuki-Miyaura Couplings between Glycosyl Aryl Boronic Acids and Iodopeptides

摘要

Suzuki-Miyaura coupling reaction was applied in the syntheses of neoglycopeptides. This work utilizes new type of glycosyl aryl boronic acid and readily accessible iodo amino acids/iodopeptides. Both carbohydrate and peptide moieties are unprotected and the final product could be isolated directly. The neoglyco amino acid and neoglycopeptide products feature an O-glycosyl biaryl linker between the carbohydrate and peptide moieties.
