Novel synthesis of 2-aminoquinoline-3-carbaldehyde, benzo[b][1,8] naphthyridines and study of their fluorescence behavior
A novel route was successfully developed for the synthesis of new synthons, orthoamino formyl quinoline (heterocyclic orthoaminoaldehyde) and utilized for the synthesis of series of benzonaphthyridines by Friedlaender condensation reactions with benzoylac
