A novel 5:8-fused heterocycle containing the imidazo[4,5-e][1,2,4]triazocine ring system has been synthesized in ten steps commencing from 1-benzyl-5-methyl-4-nitroimidazole. The compound is a new member of the family of ring-expanded xanthine–xanthosine analogues reported from this laboratory. The synthesis led to the unraveling of a number of novel rearrangements and ring-transformations.
从1-苄基-5-甲基-4-硝基咪唑开始,经过十个步骤合成了一个新的含有咪唑并[4,5- e ] [1,2,4]三唑啉环的5:8稠合杂环。该化合物是该实验室报道的扩环黄嘌呤-黄嘌呤类似物家族的新成员。综合导致解散了许多新颖的重排和环转化。
