A novel iron-catalyzed one-pot multi-component tandem reaction of acetoacetamide, urea, and two molecules of aryl aldehydes has been developed. This reaction provides a general, straightforward, practical and useful method for the preparation of potential bioactive (E)-6-arylvinyl-3,4-dihydropyrimidin-2(1H)-ones. They are also versatile precursors leading to diverse drug-like dihydropyrimidin-2(1H)-one
已开发出一种新的铁催化的乙酰乙酰胺,尿素和两分子芳基醛的单锅多组分串联反应。该反应为制备潜在的生物活性(E)-6-芳基乙烯基-3,4-二氢嘧啶-2(1 H)-酮提供了一种通用,直接,实用和有用的方法。它们还是通用的前体,可产生多种药物样的二氢嘧啶-2(1 H)-一衍生物。避免质子酸并使用单一廉价且对环境无害的催化剂的特征使该方法更有价值。
