2-a]benzotriazoles or 2,3-benzo-1,3a,6,6a-tetrazapentalenes to submit to biological assays. The derivatives were obtained by deoxycyclization reactions of appropriate nitrophenyl-1,2,3-triazole derivatives and by thermal decomposition of appropriate azidophenyl-1,2,3-triazoles (Schemes 1 and 2). Some attempts to extend these synthetic routes to the preparation of 1,2,4-triazolo[1,2-a]benzotriazoles (Scheme
本文继续合成新的1,2,3-三唑并[1,2- a ]苯并三唑或2,3-苯并-1,3a,6,6a-四氮杂戊烯,以进行生物学检测。通过适当的硝基苯基-1,2,3-三唑衍生物的脱氧环化反应和适当的叠氮苯基-1,2,3-三唑的热分解获得衍生物(方案1和2)。一些尝试将这些合成途径扩展到制备1,2,4-三唑并[1,2- a ]苯并三唑(方案3)和1,2,3-三唑并[1,2- b ] -4 H -1 ,2,3-苯并三嗪(方案4)完全失败。
