alkylative reduction of 6‐nitroquinoxaline. Catalytic reduction of 4 followed by cyclocondensation with heterocyclic malondialdehydes afforded novel 8‐(heteroaryl)‐1,4‐diethyl‐1,2,3,4‐tetrahydropyrido[2,3‐g]quinoxalines. The solutions of these novel compounds having 1,4‐diethyl‐1,2,3,4‐tetrahydroquinoxaline framework as an electron releasing system showed absorption in the range of 424–426 nm in the
1,4-二乙基-1,2,3,4-四氢-6-硝基喹喔啉4是通过6-硝基喹喔啉的烷基化反应合成的。催化还原4,然后与杂环丙二醛进行环缩合,得到新颖的8-(杂芳基)-1,4-二乙基-1,2,3,4-四氢吡啶并[2,3-g]喹喔啉。这些具有1,4-二乙基-1,2,3,4-四氢喹喔啉骨架作为电子释放系统的新型化合物的溶液在可见光区域的424-426 nm范围内显示吸收,并显示出明亮的蓝绿色荧光。通过热重分析获得的热重曲线表明,这些荧光团具有出色的热稳定性以及一步热分解的能力。J.杂环化学。(2010)。
