A new class of dihaloquinolones bearing N'-aldehydoglycosylhydrazides, mercapto-1,2,4-triazole, oxadiazoline and a-amino ester precursors: synthesis and antimicrobial activity
Reaction of the quinolones 6-8 with hydrazine afforded the hydrazide 9-11 in moderate yields. Condensation of 9 and 11 with CS2 /KOH furnished the potassium salts 13 and 14, respectively, which spontaneously afforded the 3-(1,2,4-triazolyl)-quinolones 15 and 16, respectively, on treatment with hydra...
