3-Amino-2(1H)-quinolones by Cyclizaion of N-Acylated Anthranilic Acid Derivatives
摘要:
Reaction of secondary amines with the N-(iodoacetyl)anthranilic acid derivatives, 2-(iodoacetylamino)acetophenone and 2-(iodoacetylamino)benzophenone yields 3-amino-2(1H)-quinolones in two steps. Analogously heterocondensed 5-amino-6(7H)-pyrazolo[5,4-b]pyridones were prepared. Hydroxyquinolines were subjected to Cl/OH exchange to give chloroquinolines, which are convenient for consecutive reactions.
