基于二乙基异丙基甲硅烷基(DEIPS)、甲基萘基(Nap)、烯丙基醚和乙酰丙酸(Lev)酯的使用,开发了一组新的正交保护基。保护基团非常适合制备高度支化的寡糖,并且它们的有用性已通过β-d-Man-(1→4)-d-Man二糖的化学合成得到证明,β-d-Man-(1→4)-d-Man二糖被适当保护以制备土拉弗朗西斯菌脂多糖的不寻常核心区域的一系列部分结构。
A new set of orthogonal protecting groups has been developed based on the use of a diethylisopropylsilyl (DEIPS), methylnaphthyl (Nap), allyl ether and levulinoyl (Lev) ester. The protecting groups are ideally suited for the preparation of highly branched oligosaccharides and their usefulness has been demonstrated by the chemical synthesis of a β-d-Man-(1→4)-d-Man disaccharide, which is appropriately protected for making a range of part-structures of the unusual core region of the lipopolysaccharide of Francisella tularensis.
