In rare form: Tosylated glucose derivatives are used as acceptors of the glucansucrase R from S. oralis. The tosyl groups allow only distinct orientations of the acceptor in the active cleft (docking experiments), which results in highly regioselective glucosylated products.

拓宽与甲苯磺酸底物的GTFR葡萄糖基化反应的范围，用于稀有糖的合成

在罕见的形式：甲苯磺酰化的葡萄糖衍生物用作从葡聚糖蔗糖酶的R受体口腔链球菌。甲苯磺酰基仅在活动裂隙中允许受体的不同取向（对接实验），这导致了高度区域选择性的糖基化产物。
