The present invention relates to a novel method of chemically preparing functionalized derivatives of β-(1,3)-glucans, enabling obtaining oligosaccharides which are free or which comprise specific groups such as, for example, sulphate, phosphate, methyl, in pre-defined positions. This method includes a reaction between a glycosyl donor of formula (Ia) or (Ib) and a glycosyl acceptor of formula (II), defined in the claims. Application: Preparation of biologically active compounds which can be used in the agricultural, cosmetic or pharmaceutical fields.
本发明涉及一种新颖的化学制备β-(1,3)-葡聚糖官能化衍生物的方法,使得可以获得自由或包含特定基团(如硫酸酯、磷酸酯、甲基等)的低聚糖,这些基团位于预定义的位置。该方法包括化学式(Ia)或(Ib)的糖基供体与化学式(II)的糖基受体之间的反应,所述化学式在专利权要求中定义。应用领域:制备可用于农业、化妆品或制药领域的生物活性化合物。
