The regioselective synthesis of N-alkyl pyridones can be facilitated by alkylation of 2-methoxypyridines with activated halides. The syntheses are facile and high yielding with no traces of 2-alkoxypyridines.
A new and efficient synthesis of tricyclic 4-pyridone analogs through the intramolecularHeck coupling cyclization was described. This reaction features mild conditions and good functional group tolerance allowing for the preparation of several novel tricyclic 4-pyridone analogs.
