, p. 225 - 231 (2007/10/02)
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

In order to develop new oral bronchodilators, a series of novel imidazonaphthyridin-4(5H)-ones 5 were designed and synthesized.Some of these new heterocycles exhibited more potent bronchodilator activity in vitro and in vivo than theophylline.
