E-(4-β-D-Allopyranosyloxyphenyl)-1-(4-substituted phenyl)propenone derivatives (1a–g) have been synthesized by the Claisen-Schmidt condensation of helicid with 4-substituted acetophenone using 10% NaOH aqueous solution as a catalyst. 6H-2-Amino-4-aryl-6-(4-β-D-allopyranosyloxyphenyl)-1,3-thiazine (2a–g) were synthesized by the 1,4-Michael reaction of 1a–g with thiourea. The structures of all the new products were established by 1H NMR, IR, and MS spectroscopy. Compound 2b (200 mg·kg–1) showed better sedative-hypnotic activity, so further modification of helicid should be worthwhile.
以 10%NaOH水溶液为催化剂,通过 Helicid 与 4-取代苯乙酮的 Claisen-Schmidt 缩合,合成了 E-(4-β-D-异吡喃氧基苯基)-1-(4-取代苯基)丙酮衍生物 (1a-g)。6H-2-Amino-4-aryl-6-(4-β-D-allopyranosyloxyphenyl)-1,3-thiazine (2a-g) 是由 1a-g 与硫脲发生 1,4-Michael 反应合成的。所有新产品的结构均通过 1H NMR、IR 和 MS 光谱得以确定。化合物 2b(200 mg-kg-1)显示出更好的镇静催眠活性,因此值得对 helicid 进行进一步改良。
