The bicyclic product containing a chromene skeleton and a propargylamine skeleton(C_(22)H_(22)N_2O_2) was synthesized from the double sites of terminal alkyne, piperazine derivative and formaldehyde via one-pot procedure. Its structure was characterized by ~1H NMR, ~(13)C 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) ?, β = 105.22°,V = 1750.6(3) ?~3, Z = 4, R = 0.0568 and w R = 0.1444. The fluorescence of the product was discussed.
