AbstractHerein, we report the green synthesis of a new series of benzo[d]imidazo[2,1-b]thiazole-1-ium hydroxide derivatives by a one-pot, three-component reaction of arylglyoxals, quinoline-2,4-diol, and 2-aminobenzothiazole in the presence of TEA/AcOH (1:2) as a catalyst at 50 °C in water, which appears as a green solvent. The structures of all 12 examples were confirmed by 1H NMR, 13C NMR, mass spectral
摘要在这里,我们报告通过芳基乙二醛,喹啉-2,4-的一锅三组分反应绿色合成一系列新的苯并[ d ]咪唑并[2,1 - b ]噻唑-1-鎓氢氧化物衍生物。乙二醇和2-氨基苯并噻唑在TEA / AcOH(1:2)作为催化剂的存在下于50°C的水溶液中呈绿色溶剂存在。通过1 H NMR,13 C NMR,质谱数据和FT-IR确认所有12个实施例的结构。该程序提供了温和的反应条件,使用了绿色溶剂,产率高,易于后处理,并且容易分离结构多样的三环苯并[ d ]咪唑[2,1- b ]噻唑衍生物,这些衍生物可能具有生物学和药学活性。 图形概要
