Using helicid as starting material, E-4-β-D-allopyranoside-cinnamic-4-substituted phenylketones (1a–1h) containing the structure of chalcones were synthesized; then these chalcones were reacted with guanidine hydrochloride through a 1,4-Michael reaction, giving 2-amino-4-(4-β-D-allopyranoside-phenyl)-6-3(4)substituted phenylpyrimidines (2a–2h), which were characterized by IR, 1H NMR, and HR-MS. The target compounds were evaluated by the spontaneous locomotor activity test, showing that all of them had good calming activity; compound 2f was found to have the greatest.
以helicid为起始原料,合成了含有查耳酮结构的E-4-β-D-吡喃阿洛糖苷-肉桂酸-4-取代苯基酮(1a-1h);然后通过 1,4-Michael 反应使这些查耳酮与盐酸胍反应,得到 2-氨基-4-(4-β-D-吡喃全糖苷-苯基)-6-3(4)取代苯基嘧啶(2a-2h),并通过红外光谱、1H NMR 和 HR-MS 对其进行表征。通过自发运动活性测试对目标化合物进行了评估,结果表明所有化合物都具有良好的镇静活性,其中化合物 2f 的镇静活性最高。
