Nucleophilic Chlorination of 3-Formyl-4-hydroxy-quinolin-2(1H)-ones

Chlorination of 1-substituted 3-formyl-4-hydroxy-2-quinolones (1a, b) with phosphorylchloride leads to 4-chloro-3-dichloromethylquinolones (2), which can be hydrolyzed to 4-chloro-3-formylquinolones (4).From the anilinomethylene quinolinediones (3), at lo

Organic Azides in Heterocyclic Synthesis, 12. Thermal Cyclization of 4-Azido-3-formyl-2-quinolones to Isoxazoloquinolones

Thermolysis of the 4-azido-3-formyl-2-quinolone 6, which was prepared from the 4-hydroxy-2-quinolone 1, afforded the ring-closed isoxazoloquinolone 7. 3-(Arylaminomethylene)-2,4-quinolinediones 2 could not be transformed into an azide precursor in order t
