A Cu(I)-catalyzed one-pot tandem reaction of 2-bromobenzyl bromides with 1,3-dicarbonyl compounds leading to 4H-chromene derivatives has been developed. This new approach toward 4H-chromenes combines several reactions in one pot and builds molecular complexity from readily available starting materials.
