A convenient and efficient approach for the synthesis of 5-(1-phenyl-3-phenylprop-2-ynyl)-2,2-pentylidene-1,3- dioxane-4,6-dione derivatives through a three-component reaction of aldehydes with 2,2-pentylidene-1,3-dioxane-4,6-dione and arylacetylene in the presence of Cu(OAc)2·H2O/Cu is described with 12 examples. The reaction tolerates a wide range of aldehydes furnishing the products with good to excellent isolated yields (65%~88%). Additionally, the synthetic protocol has the advantages of wild conditions, simple operation, and excessive copper reused.

Key words: multicomponent reaction, copper acetate/copper, 2,2-pentylidene-1;3-dioxane-4;6-dione, 5-(1-phenyl-3-phe- nylprop-2-ynyl)-2;2-pentylidene-1;3-dioxane-4,6-dione derivatives
