以取代邻氨基苯甲酸为起始原料,经6步反应合成了7个多取代1,4-戊二烯-3-醇(7a~7g);以7a~7g为原料,5 mol%Fe Cl3为催化剂,CH2Cl2为溶剂,于室温反应合成了7个螺环四氢喹啉衍生物(8a~8g),其结构经^1H NMR,^13C NMR,IR和HR-MS(ESI)表征。采用X-射线单晶衍射研究了8d的晶体结构。结果表明:8d的晶胞参数a=14.001(3)A°,b=12.335(2)A°,c=11.587(3)A°,α=90°,β=95.497(2)°,γ=90°,V=1 991.9(7)A°^3,Z=4,μ=0.182 mm^-1,F(000)=816.0,R[F^2〉2σ(F^2)]=0.053 7,wR(F2)=0.132 5。
Seven multi-substituted 1,4-pentadiene-3-ols(7a ~ 7g) were synthesized by a six-step reaction from substituted anthranilic acids. Seven spiro-tetrahydroquinoline compounds(8a ~ 8g) were synthesized from 7a -7g, using 5 mol% FeC13 as the catalyst and CH2Cl2 as solvent at rt. The structures were characterized by ^1H NMR, ^13C NMR, IR and HR-MS(ESI). The crystal structure of 8d was investigated by X-ray single crystal diffraction. The results indicated that the crystal parameters of 8d were a =14.001(3)A°, b =12.335(2) A°, c=11.587(3)A°, α =90°, β=95.497(2)°, Y =90°, V=1 991.9(7)A°^3, Z=4,μ=0. 182 mm^-1, F(000) =816.0, R[F^2〉2σ(F^2)] =0.053 7, wR (F^2) =0. 132 5.
