Reaction of cyclic 1,2-sulfates 2a-c with glucose directly furnished sodium 1-(glucopyranosyloxymethyl) alkyl sulfates 3a-c. Their treatment with acid led cleanly to desulfation and gave 2-hydroxyalkyl glucopyranosides 4a-c which exhibit very promising surfactant properties. The structure of these compounds were assigned via the per-O-acetyl derivatives 5a α -5c α and 5a β -5c β .
环状 1,2-硫酸盐 2a-c 与葡萄糖反应,直接生成 1-(葡吡喃氧甲基)烷基硫酸钠 3a-c。用酸对其进行处理后,可顺利脱硫,并得到 2-羟基烷基吡喃葡萄糖苷 4a-c,这些化合物具有很好的表面活性剂特性。这些化合物的结构是通过过-O-乙酰基衍生物 5a δ± -5c δ±和 5a δ² -5c δ²确定的。
