electron-donating and electron-withdrawing substituents on either para or ortho positions. Novel imidazo[2,1-b]thiazol-5-amine derivatives were synthesized by a one-pot, four-component reaction of 2-bromoacetophenone derivatives, aromatic aldehydes, thiourea, and isocyanides in the presence of ammonium chloride (NH4Cl) in toluene under reflux conditions. Moderate to good yields resulted and the reaction showed tolerance
摘要 在氯化铵(NH 4 Cl)存在下,通过2-锅苯乙酮衍生物,芳族醛,硫脲和异氰酸酯的一锅四组分反应合成了新型咪唑并[2,1 - b ]噻唑-5-胺衍生物。)在甲苯中回流条件下。产生了中等至良好的产率,反应显示出对一系列在对位或邻位带有供电子和吸电子取代基的芳族醛的耐受性。 在氯化铵(NH 4 Cl)存在下,通过2-锅苯乙酮衍生物,芳族醛,硫脲和异氰酸酯的一锅四组分反应合成了新型咪唑并[2,1 - b ]噻唑-5-胺衍生物。)在甲苯中回流条件下。产生了中等至良好的产率,反应显示出对一系列在对位或邻位带有供电子和吸电子取代基的芳族醛的耐受性。

Three Component Reaction for the Synthesis of Imidazo[2,1-b]thiazole Derivatives
Threecomponentone-pot reaction for synthesis novel of imidazo(2,1-b)thiazoles with high yield were obtained by the condensation of 4-phenylthiazol-2-amine, aromatic aldehyde and isocyanide.
