Synthesis of N‐Substituted 4‐Pyridones From Skipped Diynones via Intramolecular Base or Ag(I)‐Catalyzed Hydroamination Open
Cs 2 CO 3 or CF 3 COOAg catalyze the intramolecular 6‐endo hydroamination of the Z‐enaminones derived from the Michael‐type addition of primary amines to skipped diynones, yielding N‐substituted 4‐pyridones in good to excellent yields. The…

Organocatalyzed Approach to the Synthesis of γ‐Pyrones via Hydration/Cyclization of Skipped Diynones under Basic Conditions Open
In the presence of catalytic amounts of a secondary amine (e. g. morpholine), skipped diynones undergo hydration/cyclization in aqueous acetonitrile to form γ‐pyrones in moderate to excellent yields (30–92 %). The first step of the process…
