N-Benzyl-3-bromoazetidine (13), which was obtained by the reaction of ABB (3) with benzyl bromide, gave 3-aliphatic amino-substituted azetidine derivatives 15a, b. Novel fluoroquinolones 7a-f, 11a-f, 16a, b and 25a-c were obtained by the introduction of these azetidine derivatives into the C7 position of a quinolone nucleus 6 and N1-heterocyclic quinolones 21a-c in 21-83% yields. Some of them exhibited
