Abstract
4-Substituted 3-hydroxy-2(1H)-pyridinones 2 were prepared by Mannich reaction of 3-hydroxy-2(1H)-pyridinones with secondary amines and formaldehyde. The isolated products were then reacted with aromatic amines in the presence of NaIO3 as oxidant via oxidation–Michael addition to yield 4,5,6-trisubstituted-2,3-pyridinediones 3 in good yields (80.2–88.9%). The structures of the products were characterized by 1H NMR, ESI-MS, and IR, and elemental analysis.
