6-diarylpyrimidin-2-(1H)-ones is described. Under the experimental conditions, the main reaction products are 4,6-diarylpyrimidin-2-(1H)-ones not 4,6-diaryl-3,4-dihydropyrimidin-2(1H)-ones. The advantage of this method is to achieve improved product yields with an inexpensive and readily available catalyst, and easy experimental set-up, which provides a good method to synthesize 4,6-diarylpyrimidin-2-(1H)-ones.

摘要 介绍了一种利用PPh3/I2催化芳香酮、芳香醛和尿素三组分Biginelli反应合成4,6-二芳基嘧啶-2-(1H)-酮的方法。在实验条件下,主要反应产物是 4,6-二芳基嘧啶-2-(1H)-ones 而不是 4,6-diaryl-3,4-dihydropyrimidin-2(1H)-ones。这种方法的优点是使用廉价易得的催化剂和简单的实验装置实现了更高的产品收率,这为合成 4,6-二芳基嘧啶-2-(1H)-酮提供了一种很好的方法。图形概要
