Rapid and efficient solvent-free synthesis of 4-amino-3-mercapto-6-[2-(2-thienyl)vinyl]-1,2,4-triazin-5(4H)-one 1 under microwave irradiation is described. Some new fused heterobicyclic nitrogen systems such as 1,2,4-triazino[3,4-b][1,3,4]thiadiazinones, 1,3,4-thiadiazolo[2,3-c][1,2,4]triazinone and pyrazolo[5,1-c]-[1,2,4]triazine-7-carbonitrile, have been synthesized by treatment of 1 with bifunctional
4-amino-3-mercapto-6-[2-(2-thienyl)vinyl]-1,2,4-triazin-5(4H)-one 1 在微波辐射下快速有效的无溶剂合成。一些新的稠合杂双环氮系统,如 1,2,4-三嗪基[3,4-b][1,3,4]噻二嗪酮、1,3,4-噻二唑并[2,3-c][1,2, 4]三嗪酮和吡唑并[5,1-c]-[1,2,4]三嗪-7-腈,通过杂环化反应用双官能氧和卤素化合物、CS2/KOH和丙二腈处理1合成,在除了一些未缩合的三嗪。从元素分析和光谱数据(IR、1H-NMR、13C-NMR)推导出产物的结构。筛选出精选的新合成化合物作为抗癌剂,其中一些显示出作为针对不同癌细胞系的细胞毒剂的活性。
