- The synthesis of highly fluorescent heterocyclic compounds: Pyrido[2',1':2,3]imidazo[4,5-b]quinoline-12-yl cyanides
-
The syntheses and fluorescence properties of novel derivatives of pyrido[2',1':2,3]imidazo[4,5-. b]quinoline are described. The key intermediates (4-substituted)(3-hydroxyimino-2,3-dihydroimidazo[1,2-. a]pyridin-2-yliden)methyl cyanides were synthesized by reacting the imidazo[1,2-. a]pyridine with arylacetonitriles via nucleophilic substitution of hydrogen. The compounds were deep violet in colour. Acylation of hydroxyl group led to heterocyclization and gave highly fluorescent pyrido[2',1':2,3]imidazo[4,5-. b]quinoline.
