3-Alkyl-3-hydroxy-2,4(1H,3H)-quinolinediones 4, which are metabolites of some Pseudomonas species, were synthesized by oxidation of the corresponding 4-hydroxy-2(1H)-quinolones 3.By halogenation of 3 the 3-chloro- and 3-bromo-2,4(1H,3H)-quinolinediones 5 and 7, respectively, are obtained.Exchange of the chloro substituent in 5 with sodium azide yields the 3-azido derivative 8, while reaction with potassium fluoride affords the 3-fluoroquinolinedione 6.
