Synthesis of Benzo-halogenated 4-Hydroxy-2(1H)-quinolones
Malondianilides 3 derived from dichloro substituted anilines 2 undergo cyclization to afford 4-hydroxy-2(1H)-quinolones 4 in very good yields using methane sulfonic acid-phosphorus pentoxide as catalyst. 3,4-Dichloro anilines 5 can be shown to yield two i
