Synthesis and characterization of novel fluorescent compounds derived from 1,4-diethyl-1,2,3,4-tetrahydro-6-nitroquinoxaline

1,4‐Diethyl‐1,2,3,4‐tetrahydro‐6‐nitroquinoxaline 4 was synthesized by 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 solu...

Description
Summary:1,4‐Diethyl‐1,2,3,4‐tetrahydro‐6‐nitroquinoxaline 4 was synthesized by 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 visible region and exhibited brilliant bluish‐green fluorescence. The thermogravimetric curve obtained by thermogravimetric analysis displayed that these fluorophores possess excellent thermal stability with one‐step thermal decomposition. J.
