以豆腐果苷为原料, 与盐酸羟胺缩合反应生成4-β-D-吡喃阿洛糖苷-苯甲醛肟(2), 2与次氯酸叔丁酯发生取代反应生成4-β-D-吡喃阿洛糖苷-α-氯苯甲醛肟(3); 再将3与Schiff碱通过1,3-偶极环加成生成一系列3-(4-β-D-吡喃阿洛糖苷-苯基)-4-芳基-5-芳基-1,2,4-噁二唑啉(5a～5h). 3和 5a～5h共9个化合物均未见文献报道, 其结构经1H NMR, IR和MS (HRMS)加以确认, 并对5a～5h进行了药理活性筛选. 结果表明, 部分化合物具有良好的镇静活性. 其中, 化合物5g (200, 100 mg•kg－1)和5h (200, 100 mg•kg－1)与豆腐果苷相比较具有更强的活性.

Using helicid as a starting material, 4-β-D-allopyranosyloxy-benzaldehydeoxime (2) has been synthesized by the condensation reaction with hydroxyamine hydrochloride. Novel 4-β-D-allopyranosyloxy-α- chloro-benzaldehydeoxime (3) was synthesized by substitution reaction of 2 with t-BuOCl, and novel 3-(4-β-D-allopyranosyloxyphenyl)-4-aryl-5-aryl-1,2,4-oxadiazoline derivatives (5a～5h) have been synthesized by 1,3-dipolar cycloaddition reaction of 3 with Schiff bases 4a～4h. The new compounds 3 and 5a～5h were established by 1H NMR, IR, and MS (HRMS) spectra. The preliminary bioassay test of 5a～5h showed that some of such compounds have good calm activity. For example, com-pounds 5g (200, 100 mg•kg－1) and 5h (200, 100 mg•kg－1) were better than the parent helicid.
