以豆腐果苷为原料, 与取代苯甲酰肼反应生成中间体4-β-D-吡喃阿洛糖苷-苯甲醛取代苯甲酰腙(2a～2g), 在溴作催化剂的条件下发生关环反应, 合成了一系列豆腐果苷类似物3a～3g. 所有化合物结构经IR, 1H NMR以及MS谱得以证实. 初步药理实验结果表明, 化合物3a, 3c, 3f与豆腐果苷相比有更好的镇静活性.

A series of novel helicid derivatives containing 1,3,4-oxadiazole 3a～3g were successfully synthesized from the intermediates aryl-3-carbonyl (4-β-D-allopyranoside-yl)-benzaldehyde hydrazone derivatives (2a～2g), which prepared starting from helicid. The new compounds were characterized by 1H NMR, IR and HR-MS spectra. The sedative-hypnotic activities of the target compounds 3a～3g were evaluated by testing the spontaneous locomotor activity in mice. All of the derivatives produced moderate to high activities. In particularly, compound 3c presented the most potent sedative-hypnotic effect in comparison to the other derivatives, and compounds 3a and 3f also showed potent activities.
