摘要

Abstract 3-Alkl-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 substitutent in 5 with sodium azide yields the 3-azido derivatives 8, while reaction with potassium fluoride ...
