摘 要:以豆腐果苷为原料,与4-取代苯乙酮发生Claisen-Schimidt反应,得到一系列E-4-β-D-吡喃阿洛糖苷-苯乙烯基-4-取代苯酮衍生物1a~1e,再将1a~1e与邻氨基苯硫酚发生1,4-Michael反应,得到2-(4-β-D-吡喃阿洛糖苷-苯基)-4-芳基-2,3-二氢-1,5-苯并硫氮杂衍生物2a~2e,以上化合物均未见文献报道,其结构经1H NMR,IR,MS加以确证,并对2a~2e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2a(200mg·kg-1),2b(200mg·kg-1),2c(200mg·kg-1),2d(200mg·kg-1),2e(200mg·kg-1)与豆腐果苷相比较具有更强的活性.Using helicid as starting material, novel E-(4-β-D-allopyranosyloxyphenyl)-1-(4-substituted phenyl)propenone derivatives (1a - 1e) have been synthesized by Claisen-Schimidt reaction with 4-substituted hypnone. 2-(4-β-D-Allopyranosyloxyphenyl)-4-aryl-2,3-dihydro-1,5-benzothiazepine derivafives (2a-2e) have been synthesized by 1,4-Michael reaction with ladle. The new compounds were established by ^1H NMR, IR and MS spectra. The preliminary bioassay test of 2a-2e suggested that some of them should show good calm activity. For example, compounds 2a (200 mg·kg^-1), 2b (200 mg·k^g-1), 2c (200 mg·kg^-1), 2d (200 mg·kg^-1) and 2e (200 mg·kg^-1) were better than the parent helicid.
