An efficient two-step route for the synthesis of carbamate-tethered glycosylated amino acids by coupling of oxycarbonyl chlorides derived from side-chain hydroxyl group of N α-Fmoc-Ser, Thr, Tyr and homoserine (Hser) with appropriately protected sugar-1-amine has been described. The utility of these neoglycoamino acids as building blocks for the synthesis of neoglycopeptides possessing the carbamate moiety has been demonstrated.
高效的两步路线用于合成由羧酸氯化物(来源于 N α -Fmoc-Ser、Thr、Tyr 和同丝氨酸 Hser 的侧链羟基)与适保护的糖胺1偶联制备的碳酸酰胺键连接的糖基化氨基酸。这些新糖基氨基酸作为合成具有碳酸酰胺基团的新糖肽的构建模块的实用性已得到证明。
