A Cu(I)-catalyzed highly regioselective domino reaction of 2,3-dibromo-1-propenes with β-ketoesters and 1,3-diketones, respectively, in DMF at 120 °C using Cs2CO3 as a base and hydroquinone as an additive delivers 2,3,5-trisubstituted furans and related compounds with good yields via an intermolecular C-allylation followed by an intramolecular Ullmann type O-vinylation and a double bond isomerization.
