    conditions have been found to carry out the Biginelli reaction for the synthesis of 3,4-dihydropyrimidin-2(1H)-one derivatives. This synthesis was performed using potassium hydrogen sulfate as the promoter in glycol solution. Compared with the classical Biginelli reaction conditions, this new method has the advantage of excellent yields (85-99%) and short reaction time (0.5-2 h).
    已经发现简单和改进的条件可以进行 Biginelli 反应以合成 3,4-二氢嘧啶-2(1H)-one 衍生物。该合成是在乙二醇溶液中使用硫酸氢钾作为促进剂进行的。与经典的 Biginelli 反应条件相比,这种新方法具有收率高(85-99%)和反应时间短(0.5-2 h)的优点。
