of 2,6-disubstituted pyrimidin-4(3H)-ones with 1,3-dicarbonyl compounds and some aromatic and heterocyclic aldehydes on heating or under microwave irradiation afforded new functionally substituted 5,8-dihydropyrido[2,3-d]pyrimidin-4(3H)-ones. Conventional heating was found to be more advantageous. The effects of the 2-substituent in the initial pyrimidin-4(3H)-one and the nature of the dicarbonyl component
2,6-二取代的嘧啶-4(3 H)-与1,3-二羰基化合物以及一些芳香族和杂环醛的一步三组分缩合反应在加热或微波辐射下进行,得到了新的功能取代的5,8-二氢吡啶基[2,3 - d ]嘧啶-4(3H)-1。发现常规加热是更有利的。分析了最初的嘧啶-4(3 H)-中的2-取代基和二羰基组分的性质对产物结构和产率的影响。
