Abstract:The title compound 5-(furan-2-yl) -3,4,4α ,5,6,10b-hexahydro-2H-pyrano 3,2-c ] quinoline was synthesized by GdCl3/KI catalyzed aza-Diels-Alder reaction. The crystal structure of the cis isomer was determined by X-ray single-crystal diffraction analysis. The crystal belongs to monoclinic, space group P21/c with unit cell dimensions α = 0.9595(2) nm,b =0.955 8(2) nm,c =1.4164(3) nm,β=95.692(4)°,V=1.292 6(5) nm^3,Z=4,F(000) = 544,M = 255.31,D = 1.312 g/cm^3,μ( MoKα) = 0. 086 mm^- 1. The final R = 0. 056 0, ωR = 0.113 4 for 2 132 observed reflections with I 〉 2σ(I).
