The synthesis of novel 7-amino-substituted pyrazolo[1,5-a][1,3,5]triazine-8-carbonitriles was achieved via a three-component reaction of 3-amino-substituted 5-aminopyrazole-4-carbonitriles, cyanamide and triethyl orthoformate under microwave irradiation. Under catalyst-free conditions, this three-component reaction accommodated a generous diversity of amino substituents making it ideal for the generation
新型7-氨基取代的吡唑并[1,5- a ] [1,3,5]三嗪-8-腈的合成是通过3-氨基取代的5-氨基吡唑-4-腈的三组分反应实现的,微波辐射下的氰胺和原甲酸三乙酯。在无催化剂的条件下,该三组分反应可容纳大量的氨基取代基,因此非常适合用于药物开发过程的化合物库的生成。
