The reaction of enamine between 9-chloroacridines and 6-aminouracil derivatives give novel acridine substituted uracils, the structures of which have been determined by means of an X-ray analysis of 5-(acridin-9-yl)-6-amino-1,3-dimethyluracil hydrochloride dihydrate, C19H16N4O2·HCl·2H2O. The crystal is triclinic with a space group P\bar1; also, a=8.763(3) b=16.130(9), c=7.620(2) A, α=117.51(4), β=83
9-氯吖啶和 6-氨基尿嘧啶衍生物之间的烯胺反应得到新的吖啶取代尿嘧啶,其结构已通过 5-(吖啶-9-基)-6-氨基-1 的 X 射线分析确定,3-二甲基尿嘧啶盐酸盐二水合物,C19H16N4O2·HCl·2H2O。晶体为三斜晶系,空间群为P\bar1;另外,a=8.763(3) b=16.130(9), c=7.620(2) A, α=117.51(4), β=83.81(3), γ=94.21(4)°, Z=2, V =949.3 A3,Dc=1.16 g cm-3,CuKα μ=5.30 cm-1。该结构通过直接方法求解并通过块对角最小二乘法进行改进:对于 |Fo|>3σ(|Fo|) 的 2810 次反射,R=0.074。该晶体由标题化合物、氯阴离子和两个通过氢键结合在一起的水分子组成(见表 4)。
