area has been used as a novel and efficient catalyst for an improved and rapid synthesis of biologically active 2,4,5-trisubstituted imidazoles, by three-component, one-pot condensation of 1,2-diketones and aryl aldehydes, in excellent yields under solvent-free and conventional heating conditions. The method has several advantages, for example excellent yields, shorter reaction time, and use of a non-toxic
摘要具有高比表面积的纳米晶氧化镁已被用作新型,有效的催化剂,用于通过三组分一锅缩合的1,2-二酮来改进和快速合成具有生物活性的2,4,5-三取代的咪唑和芳基醛,在无溶剂和常规加热条件下,收率极高。该方法具有多个优点,例如优异的产率,较短的反应时间以及使用无毒且可回收的催化剂。 图形概要
