Nucleophilic Substitution and Ring Closure Reactions of 4-Chloro-3-nitro-2-quinolones

4-Chloro-3-nitro-2-quinolones 3 obtained from the 4-hydroxy quinolones 1 by nitration and chlorination, reacted with sodium azide to the 4-azido derivatives 4 which cyclized on thermolysis to yield the furoxanes 5.Nucleophilic substitution reactions of 3
