摘　　要：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.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.
