Dehydrative glycosylation using 2,3,4,6-tetra-O-benzyl-D-glucopyranose was carried out by the use of a condensing reagent system composed of diethylaminosulfur trifluoride (DAST), tin(II) triflate, tetrabutylammonium perchlorate, and triethylamine. Using this system, two tetrasaccharides, O-α-D-glucopyranosyl-(1→4)-O-α-D-glucopyranosyl-(1→3)-O-α-D-glucopyranosyl-(1→4)-D-glucopyranose and O-α-D-glu
通过使用由二乙氨基三氟化硫 (DAST)、三氟甲磺酸锡 (II)、四丁基高氯酸铵和三乙胺组成的缩合试剂系统,使用 2,3,4,6-四-O-苄基-D-吡喃葡萄糖进行脱水糖基化. 使用该系统,两种四糖,O-α-D-吡喃葡萄糖基-(1→4)-O-α-D-吡喃葡萄糖基-(1→3)-O-α-D-吡喃葡萄糖基-(1→4)-D -吡喃葡萄糖和 O-α-D-吡喃葡萄糖基-(1→3)-O-α-D-吡喃葡萄糖基-(1→4)-O-α-D-吡喃葡萄糖基-(1→4)-D-吡喃葡萄糖合成的。
