  Et₃N-Induced Demethylation−Annulation of 3-Alkynyl-4-methoxy-2-pyridones and Structurally Related Compounds in the Synthesis of Furan-Fused Heterocycles

  摘要：

  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 S(N)2 process has been established that accounts for the dealkylation process.
