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 bromid...
