indicating an important role in biological activity for the benzene ring with electron-withdrawing substituents. These compounds show the best MIC50 against C. guilliermondii and C. glabrata, respectively. The current findings suggest that the 3-benzoyl imidazo[1,2-a]pyrimidinederivatives, herein synthesized by an accessible methodology, are potential antifungal drugs.

A convenient one-pot, three-component reaction has been developed for the synthesis of 3-aroylimidazo[1,2-a]-N-heterocycles from aryl ketones and 2-amino-N-heterocycles using dimethyl sulfoxide as a methylene donor. The reaction proceeds smoothly catalyzed by I2 in the presence of K2S2O8 and affords the desired products in moderate to good yields. This protocol offers significant superiority in accessing
已经开发了一种方便的一锅三组分反应,用于使用二甲基亚砜作为亚甲基供体,从芳基酮和2-氨基-N-杂环合成3-芳基咪唑并[1,2- a ] -N-杂环。在K 2 S 2 O 8的存在下,反应被I 2平稳催化,并以中等至良好的产率提供所需的产物。该协议在访问具有各种取代方式的生物活性3-芳基咪唑并[1,2- a ] -N-杂环时具有显着优势。
