Pentacyclic heterocyclic compounds containing a 1,2,4-triazole ring have been synthesized from [5-(2-methylpropyl)-1,2,3,4-tetrahydropyrimido[4′,5′: 4,5]thieno[2,3-c]isoquinolin-8-yl]hydrazine. The synthesized [1,2,4]triazolo[4,3-c]pyrimidine derivatives have been found to undergo Dimroth rearrangement in both acidic and basic media.
含1,2,4-三唑环的五环杂环化合物是由[5-(2-甲基丙基)-1,2,3,4-四氢嘧啶基[4',5':4,5]噻吩并[2, 3 - c ]异喹啉-8-基]肼。已经发现合成的[1,2,4]三唑并[4,3- c ]嘧啶衍生物在酸性和碱性介质中都发生了狄莫罗特重排。
