series of fluorinated spiro[1,5-benzothiazepin-2,3′[3′H]-indol]-2′(1′H)-ones have been prepared by the reaction of 2-aminobenzene-thiols with 1,3-dihydro-3-[2-phenyl/(4-fluorophenyl)-2-oxoethylidene)-indol-2(1H)-ones (I) under microwave irradiation in open vessels using ethylene glycol as energy transfer medium and thermally in absolute ethanol saturated with hydrogen chloride gas. The comparative
一系列氟化的螺[1,5-苯并硫氮杂-2,3' - [3' ħ ] -吲哚] -2'(1' ħ) -酮制备了的2-氨基苯硫醇与1,3-反应-二氢-3- [2-苯基/(4-氟苯基)-2-氧代亚乙基)-吲哚-2(1 H)-一个(I),在敞口容器中以乙二醇为能量传递介质并在绝对绝对条件下进行热辐射乙醇用氯化氢气体饱和。比较研究表明,与传统方法相比,微波辅助有机合成具有明显减少反应时间,提高收率和更清洁反应的优点。所有合成的化合物均已通过分析和光谱数据进行了表征,并筛选了它们的抗真菌活性链格孢和尖孢镰刀菌和抗结核活性针对结核分枝杆菌IVb族(R = F,X = F)和IVe的(R = F,X = CH 3)在减少的真菌生长所示高于90%的抑制格孢而IVA( R = H,X-F)在初次筛查时显示出98%的抗结核活性。
