diazomethane gave the N-3 methyl derivative (6) and a mixture of the N-3, O-dimethyl derivative (9), the N-1, N-3-dimethyl derivative (10) and the O-methyl derivative (11), respectively. 5-Carbamoyl-1-methylimidazolium-4-olate (7) and its 4-carbamoyl isomer (16) were prepared from 2-aminopropanediamides 8 and 15, respectively. Treatment of the imidazolium compound (10) with aqueous potassium hydroxide
用各种酰基氯酰化4-氨基甲酰基咪唑鎓5-油酸酯(2),产生4(5)-氨基甲酰基-1 H-咪唑-5-(4)酰基羧酸酯(3a-j)。用氢氧化钠处理酯3a,c,得到酰亚胺4a,c。3a和2用重氮甲烷甲基化得到N -3甲基衍生物(6)和N -3,O-二甲基衍生物(9),N -1,N -3-二甲基衍生物(10)和N -3的混合物邻甲基衍生物(11), 分别。由2-氨基丙烷二酰胺8和15分别制备5-氨基甲酸酯基-1-甲基咪唑-4-油酸酯(7)及其4-氨基甲酰基异构体(16)。用氢氧化钾水溶液处理咪唑鎓化合物(10),得到再循环的产物1-甲基-5-甲基氨基甲酰咪唑鎓4-油酸酯(18)。除16之外的甲基衍生物6、7和9证明对小鼠的Lewis肺癌或肉瘤180完全缺乏抗肿瘤活性。
