A series of mannosyl donors linked via position 2 to an m-xylylene or an isophthaloyl spacer which was connected to the position 6 of a glucoside acceptor afforded, via intramolecular glycosylation, the corresponding disaccharides with high beta anomeric ratio.
一系列甘露糖基供体经由位置2连接至间二甲苯基或间苯二甲酰基间隔基,所述间二甲苯基或间苯二甲酰基间隔基连接至葡糖苷受体的位置6,通过分子内糖基化提供具有高β异头物比率的相应二糖。
