The three-component reaction of malononitrile, aldehydes and thiourea/urea, is applied to the formation of
pyrimidine derivatives. The reaction occurs at best in EtOH at reflux, in the presence of high surface area and nanosized
MgO. This methodology is more convenient to compare with alternative ways because it needs shorter reaction times, allows
straightforward product isolation, and provides higher yields.

丙烯腈、醛和
硫脲/
尿素用于 pyrimidine 衍
生物的合成。该反应在高表面积和纳米级 MgO 存在下,在
乙醇中回流进行效果最佳。这种方法相比于其他替代方法更为便利,因为它需要更短的反应时间,便于产品的直接分离,并且具有更高的产率。
