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.

vitro xanthineoxidase (XO) inhibitory activity for the first time. Structure‐activity relationship analyses are also presented. Among the synthesized compounds, VA‐5, ‐9, ‐10, ‐12, ‐22, ‐23, and ‐25 were the active inhibitors with IC50 values ranging from 6.45 to 13.46 µM. Compound VA‐25 with a pyridinyl ring as ring A and a thiophenyl ring as ring B emerged as the most potent XO inhibitor (IC50 = 6
在无溶剂条件下,在微波反应器中使用二氧化硅负载的氟硼酸合成了一系列 4,6-二芳基/杂芳基嘧啶酮。详细研究了 HBF4-SiO2 的催化影响以优化反应条件。首次评估了合成化合物的体外黄嘌呤氧化酶 (XO) 抑制活性。还提供了构效关系分析。在合成的化合物中,VA-5、-9、-10、-12、-22、-23和-25是活性抑制剂,IC50值为6.45至13.46 μM。与别嘌呤醇 (IC50 = 12.24 µM) 相比,具有吡啶基环作为环 A 和苯硫基环作为环 B 的化合物 VA-25 成为最有效的 XO 抑制剂 (IC50 = 6.45 µM)。

Abstract An efficient and facile synthesis of 4,6-diarylpyrimidin-2(1H)-one via a Biginelli-like reaction of aromatic aldehydes, aromatic ketones, and urea in the presence of NaOH undersolvent-free conditions using a heating method has been developed. Compared with the classical reaction conditions, this new synthetic method has the advantages of excellent yields, shorter reaction time, and mild reaction
