3-Alkynyl-4-methoxypyridin-2(1H)-ones undergo cyclization via divergent pathways when heated in acetic acid or triethylamine as reagent-solvent under microwave irradiation to furnish selectively furo[2,3-b]pyridin-4-ones or their regioisomeric furo[3,2-c]

(Chemical Equation Presented) Various 3-iodo-4-methoxypyridin-2-ones and related pyrone and coumarin derivatives have been demonstrated as readily available precursors of 2-substituted furan-fused heterocycles by means of in situ sequential Sonogashira-acetylide coupling, dealkylation, and regioselective furan annulation reactions. A Et3N-induced SN2 process has been established that accounts for the dealkylation process.
