A one-pot two-step three-component process for the synthesis of trifluoromethylated 2-hydroxy-5-oxo-3,4,5,6,7,8-hexahydro-2H-chromenes has been developed. The three-component reaction of dimedone, substituted benzaldehydes, and methyl 4,4,4-trifluorobut-2-ynoate gave the desired products in moderate to good yields. Excellent regioselectivity and diastereoselectivity were observed. Furthermore, refluxing the product chromenes with p-toluenesulfonic acid in toluene gave the corresponding dehydrated products - trifluoromethylated 5-oxo-5,6,7,8-tetrahydro-4H-chromenes.
