The gold-catalyzed intermolecular addition of 1,3-dicarbonyl compounds to unactivated 1-alkynes (Nakamura reaction) is achieved at room temperature for the first time through synergistic gold/gallium catalysis. The developed system is highly efficient with a gold catalyst loading that can be as low as 500 ppm.
