4-aminoimidazo[5,1-с][1,2,4]triazine-3,8-dicarboxylate in reactions with nucleophiles and demonstrated the possibility of selective formation of monoamides by interaction with primary and secondary aliphatic amines. It was determined that the carbon atom at position 4 of imidazo[1,5-с][1,2,4]triazine system underwent nucleophilic attack, enabling the synthesis of imidazo-[1',5':3,4][1,2,4]triazino[5,6-b][1
我们研究了4-氨基咪唑并[5,1-с] [1,2,4]三嗪-3,8-二羧酸二乙酯在与亲核试剂反应中的反应性,并证明了通过与伯和仲脂族相互作用选择性形成单酰胺的可能性胺类。已确定咪唑[1,5-с] [1,2,4]三嗪系统第4位的碳原子受到亲核攻击,从而能够合成咪唑-[1',5':3,4] [ 1,2,4]三嗪并[5,6-b] [1,5]苯并x氮平和咪唑并[1',5':3,4] [1,2,4]三嗪并[5,6-b] [1 ,5]-苯二氮卓类以及(吡唑-4-亚甲基肼基)咪唑,具体取决于所使用的双亲核试剂。
