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

, p. 128 - 134 (2007/10/02)
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
