A convenient protection-free synthetic route for the preparation of alkyl glycosides has been developed. The alcoholysis of one-step preparable glycosyl donors, 4,6-dibenzyloxy-1,3,5-triazin-2-yl (DBT) glycosides, under hydrogenolytic conditions gave the corresponding glycosides in good yields without the addition of any acid promoters. The method could be successfully applied to the glycosylation of an acid-labile oligosaccharide.
已开发出一种方便的无保护合成路线用于烷基糖苷的制备。在氢解条件下,一步可制备的糖苷供体4,6-二苯氧基-1,3,5-三嗪-2-基(DBT)糖苷的醇解反应,能够在不添加任何酸催化剂的情况下,以良好的产率得到相应的糖苷。该方法可以成功应用于酸不稳定的寡糖的糖基化。
