CuO catalyzes a three-component reaction of α-ketoaldehydes, 1,3-dicarbonyl compounds, and organic boronic acids in water to provide a wide range of products containing 1,3- and 1,4-diketones. The method offers use of readily available starting materials, wide substrate scope, excellent yields, gram-scale synthesis, and mild reaction conditions.
