4-dihydroimidazo[5,1-c][1,2,4]triazines was developed which significantly expanded the scope of these compounds for further studies of their biological activity. The structure and photophysical properties of the synthesized bicyclic heterocycles containing a 1,2,3-thiadiazole ring and several functional groups have been studied. The features of their absorption and emission are revealed, and preliminary directions
详细研究 β-1,2,3-噻二唑烯胺与含有重氮官能团的唑类的相互作用,可以确定 5-重氮唑盐和 5-重氮唑反应性的差异,从而导致实施各种反应机理和芳族或非芳族双环体系的形成。通过核磁共振光谱监测这种转变揭示了关键的不稳定中间体,该中间体在低温下被进一步分离,从而获得了指定结构的证据。一种制备新型 1,4-二氢吡唑并[5,1- c ][1,2,4]三嗪和 1,4-二氢咪唑[5,1 - c ] 的有效 PASE 方法][1,2,4]三嗪的开发显着扩大了这些化合物的范围,以进一步研究其生物活性。已经研究了合成的含有1,2,3-噻二唑环和几个官能团的双环杂环的结构和光物理性质。揭示了它们的吸收和发射特性,初步概述了它们作为新型荧光传感器的应用方向。
