Pyrones are important structural units in natural products and synthetic functional molecules. Here, we report a carbene‐catalyzed oxidative [3+3] cycloaddition reaction between enals and nitrogen ylides for quick access to 2‐pyrones. Inexpensive and easily prepared 2′‐pyridinium acetophenone bromide salts are used as precursors of pyridinium ylides to react with enals in our catalytic reactions.
