synthesized via a rapid, one-pot, three-component reaction by using La(NO3)3·6H2O as an efficient catalyst from the reaction of 2-aminobenzimidazole, aromatic aldehydes and thioglycolic acid in ethanol at room temperature. These new compounds were characterized by IR, 1H, 13C NMR and mass spectroscopies. An inexpensive and available catalyst, short reaction time, easy workup, good to excellent yields
利用La(NO 3)3 ·6H 2 O作为高效催化剂,通过快速的一锅三组分反应合成了一系列3-benzimidazolyl-2-aryl thiazolidinones,4a–j的新衍生物。室温下2-氨基苯并咪唑,芳香醛和巯基乙酸在乙醇中的反应 这些新化合物的特征在于IR,1 H,13 C NMR和质谱。该反应的优点是廉价且可得到的催化剂,反应时间短,易于后处理,良好至优异的收率和无毒溶剂。
