In this study, a new synthetic approach to 4,5-branched Kdo trisaccharides based on the common acceptor Kdo(α2-4)Kdo was developed. The synthesis of three types of 4,5-branched trisaccharides, Hep(α1-5)[Kdo(α2-4)]Kdo, Man(α1-5)[Kdo(α2-4)]Kdo, and GalNAc(α1-5)[Kdo(α2-4)]Kdo, was achieved in good yield and high α-selectivity.
在这项研究中,开发了一种基于共同受体Kdo(α2-4)Kdo的4,5支化Kdo三糖合成方法。Hep(α1-5)[Kdo(α2-4)] Kdo,Man(α1-5)[Kdo(α2-4)] Kdo和GalNAc(α1-)三种3,4,5支三糖的合成5)以高收率和高α-选择性获得[Kdo(α2-4)] Kdo。
