The one-pot assembly of 4-alkoxy-3-iodo-2-pyridones, terminal alkynes, and organic halides has been achieved by integration of two sequential palladium-mediated cross-coupling reactions−Sonogashira and Wacker-type heteroannulation processes−and subsequent deprotection of the alkoxy group to afford furo[2,3-b]pyridones.
