A very simple and efficient procedure for the synthesis of novel 2-hydroxy-4H-pyrimido(1,2-a]pyrimidin-4-ones is described. Title compounds were obtained from the room temperature reaction of 2-aminopyrimidine and its substituted derivatives with bis(2,4,6-trichlorophenyl) malonates. High product yields were observed under optimized conditions. Applicability and reactivity of a range of substituted
描述了一种非常简单有效的合成新型 2-羟基-4H-嘧啶 (1,2-a] 嘧啶-4-酮的方法。标题化合物是从 2-氨基嘧啶及其取代衍生物的室温反应中获得的双(2,4,6-三氯苯基)丙二酸酯。在优化条件下观察到高产率。还研究了一系列取代和未取代的苯基丙二酸酯的适用性和反应性。所有新化合物的结构鉴定都是通过光谱方法和元素分析。
