摘 要:以5-苯基-1,3-环己二酮,醛,乙酰乙酸乙酯(或乙酰丙酮)和乙酸铵为原料,在无水乙醇中经一锅反应合成了14个新型的7-苯基-1,4,5,6,7,8-六氢喹啉酮衍生物,总收率85%-95%,其结构经1HNMR,13CNMR,IR和HR-MS表征。采用X-ray单晶衍射研究了2-甲基-4,7-二苯基-5-氧代-1,4,5,6,7,8-六氢喹啉顺反异构体(5a和5a’)的晶体结构。结果表明:5a空间群为C2/c,a=9.45835(19)A,b=19.7890(4)A,c=11.0409(2)A,α=90°,β=105.614(2)°,γ=90°,V=1990.28(7)A3,Z=4,μ=0.673mm-1,F(000)=824;5a’空间群为C2/c,a=9.7702(5)A,b=19.9810(10)A,c=10.4301(4)A,α=90°,β=98.361(5)°,γ=90°,V=2014.51(17)A3,Z=4,μ=0.665mm-1,F(000)=824。Fourteen 7-phenyl-1,4,5,6,7,8-hexahydroquinolinone derivatives, in total yields of 85% -95%, were synthesized by one-pot method in EtOH, using 5-phenyl-1,3-cyclohexanedione, alde- hydes, ethyl aeetoacetate (or acetylactone) and ammonium acetate as the materials. The structures were characterized by 1 H NMR, 13C NMR, IR and HR-MS. The crystal structures of ethyl 4,7-diphenyl-2-methyl-5-oxo-1,4,5,6,7,8-hexahydroquinolin-3-carboxylate ( 5a and 5a') were investigated by X-ray single crystal diffraction. The results indicated that 5a belongs to space group C2/c with a = 9.458 35(19) A, b = 19. 789 0(4) A, c = 11.040 9(2) A, α =90°,β = 105. 614(2)°, γ =90°, V= 1 990.28(7) A3, Z =4, μ =0.673 mm-1, F(000) =824. 5a' belongs to space group C2/c with a =9.770 2(5) A, b =19.981 0(10) A, c=10.430 1(4) A, α =90°, β=98.361(5)°, γ=90°, V=2 014.51(17) A3, Z =4, μ =0.665 mm-1, F(000) =824.
