使用简便、易得的3-(4-甲氧基苯甲酰亚甲基)羟吲哚和3-(4-氟苯基氨基)-2-环己烯-1-酮为原料,在乙醇钠和乙醇的共同作用下,一步合成得到5-(4-氟苯基)-11-(4-甲氧基苯基)-1H-吲哚[2,3-b]喹啉-1-酮化合物。通过单晶X衍射法确定其结构,晶体属单斜晶系,空间群Cc,分子量Mr=537.57(包含1分子溶剂DMF),晶胞参数a=1.44352(3)nm,b=2.6027(3)nm,c=0.93423(8)nm,V=2.6917(4)nm3,Z=4,晶胞密度Dc=1.327 Mg/m3,吸收系数μ=0.093 mm-1,单胞中电子的数目F(000)=1128。晶体结构用直接法解出,经全矩阵最小二乘法对原子参数进行修正,最终的偏离因子为R=0.0631,Rω=0.1535。在晶体结构中新形成的含氮六元杂环近似于平面结构。
The starting material was 3- (4-methoxybenzylidene) oxindole and 3- (4-fluorophenylamino) -2-cyclohexen-1-one Synthesis of 5- (4-fluorophenyl) -11- (4-methoxyphenyl) -1H-indolo [2,3-b] quinolin-1-one by one-step synthesis of sodium and ethanol Compound. The crystal structure is monoclinic X-ray diffraction. The crystal belongs to the monoclinic space group Cc, the molecular weight Mr = 537.57 (including one molecule of solvent DMF), the unit cell parameter a = 1.44352 (3) nm, b = 2.6027 (3) nm, c = 0.93423 (8) nm, V = 2.6917 (4) nm3, Z = 4, cell density Dc = 1.327 Mg / m3 and absorption coefficient μ = 0.093 mm-1. ) = 1128. The crystal structure was solved by the direct method. The atomic parameters were corrected by full matrix least square method. The final deviation factor was R = 0.0631 and Rω = 0.1535. The newly formed nitrogen-containing six-membered heterocyclic ring in the crystal structure approximates the planar structure.
