5]triazin-6-one scaffold was successfully achieved by the introduction of substituents into positions 2 and 7 via two complementary approaches for the synthesis of key intermediates viz. pyrimidinylguanidines. Variations in position 4 of the pyrimido[1,2-a][1,3,5]triazine ring were made available by the regioselective introduction of various substituents via the triazine ring closure with corresponding aldehydes
开发了一种制备在环的2、4和7位官能化的新型嘧啶并[1,2- a ] [1,3,5]三嗪-6-衍生物的方法。嘧啶并[1,2- a ] [1,3,5]三嗪-6-一个骨架的衍生化多样性是通过两种互补方法将取代基引入位置2和7来合成关键中间体而成功实现的即 嘧啶基胍。嘧啶并[1,2- a ] [1,3,5]三嗪环第4位的变化可通过以下方法实现:三嗪与相应的醛一起闭环。该方法的范围通过制备66个嘧啶并[1,2- a ] [1,3,5] triazin-6- one的文库进行了说明,事实证明该文库是新的选择性抗癌药的来源。还研究了所制备化合物的互变异构偏好性和抗癌特性。
