The bicyclic product containing a chromene skeleton and a propargylamine skeleton (C22H22N2O2) was synthesized from the double sites of terminal alkyne, piperazine derivative and formaldehyde via one-pot procedure. Its structure was characterized by 1H NMR, 13C NMR, IR and H RMS, and further confirmed by single-crystal X-ray diffraction. It crystallizes in the monoclinic system, space group P21/n with a=12.6571(14), b=11.3249(12), c=12.6571(14)Å, β=105.22°, V=1750.6(3)Å3, Z=4, R=0.0568 and wR=0.1444. The fluorescence of the product was discussed.
