A novel four component modified Biginelli reaction for the synthesis of C-2 functionalized dihydropyrimidines has been established. The approach uses assembly of less explored acetyl acetone with aromatic aldehyde, thiourea, and dimethyl sulphate to construct a novel 5-acetyl 2-methylthio dihydropyrimidine system, which works as an efficient well-designed intermediate for generating C-2 modified Biginelli
建立了一种用于合成 C-2 官能化二氢嘧啶的新型四组分改进 Biginelli 反应。该方法利用较少探索的乙酰丙酮与芳香醛、硫脲和硫酸二甲酯的组装来构建新型的 5-乙酰基 2-甲硫基二氢嘧啶系统,该系统可作为一种高效、精心设计的中间体,用于生成带有氮的 C-2 修饰 Biginelli 文库亲核试剂。苯肼、氨基脲和芳基氨基脲被成功地用作N-亲核试剂,生成C-2功能化的二氢嘧啶衍生物,满足活性药效基团的要求。时间经济、步骤经济以及单锅反应具有中等至优异的产率是这种新方法的主要优点。
