AbstractA convenient synthesis of N-phenacylbenzimidazoles in high yields (90–95%) by the N-alkylation reaction of 1H-benzimidazole with phenacyl bromides is provided. The carbonyl group reduction in the products offered the respective N-(2-aryl-2-hydroxyethyl)benzimidazoles in yields up to 97%. In the optimization of reaction conditions for preparing these N-substituted benzimidazoles (ketones and
抽象的一种方便的合成Ñ -phenacylbenzimidazoles以高产率(90-95%)由Ñ 1的烷基化反应ħ设置有苯甲酰甲基溴化物-苯并咪唑。产物中羰基的还原提供各自的N-(2-芳基-2-羟乙基)苯并咪唑,产率高达97%。在优化用于制备这些N-取代的苯并咪唑(酮和醇)的反应条件时,描述了环保方法(微波和超声)与常规加热之间的比较研究。测试了这些抗真菌唑类类似物对白色念珠菌和新隐球菌的体外抗真菌活性。,其中氯取代的醇(4-Cl和2,4-Cl 2)显示出最佳的活性(MIC 50 = 31.2×10 –6 g / cm 3)。 图形摘要
