A new, direct, and efficient synthesis of benzonaphthyridin-5-ones
摘要:
Microwave-assisted Suzuki cross-coupling reaction of 2-fluorophenylboronic acid with all orthochlorocyanopyridine isomers allowed the rapid syntheses of key intermediates for anionic ring closure, which was performed using potassium hydroxide under microwave irradiation to give benzonaphthyridin-5-ones in high yields.
