Five 2-aroyl-3-aryl-5H-furo[3,2-g]chromene derivatives have been synthesized, and their structures were characterized by IR, NMR, ESI-MS and elemental analysis. The crystalstructure for 2-benzoyl-3-(4-methoxyphenyl)-6,7-dihydro-5H-furo[3,2-g]chromene has been determined by single-crystal X-ray diffraction. X-ray analysis reveals that the pyran ring adopts a half-chair conformation, while the fused
