Abstract

A gold-catalyzed post-Ugi cascade transformation for the synthesis of 2-pyridones is described. The process involves furan–alkyne cyclization followed by furan ring-opening and cleavage of the isocyanide-originated fragment. The initially formed cis double bond can isomerize into a more stable trans double bond upon prolonged exposure to a strong Brønsted acid. Thus, the overall strategy provides a viable access towards two types of 2-pyridones.
