Three novel ring systems, namely the thieno[3,4-d]-1,2,4-triazolo[1,5-a]pyrimidine, the thieno[3,4-e]-1,2,4-triazolo[1,5-a]pyrimidine and the thieno[3,2-d]-1,2,4-triazolo[1,5-a]pyrimidine were synthesised. The structure of compounds obtained was proved with the help of their uv and cmr spectra using model compounds prepared for this purpose.
三种新颖的环系统,即噻吩并[3,4- d ] -1,2,4-三唑并[1,5- a ]嘧啶,噻吩并[3,4- e ] -1,2,4-三唑并[ 1,5-一个]嘧啶和噻吩并[3,2- d〕-1,2,4-三唑并〔1,5-一个]嘧啶合成。使用为此目的制备的模型化合物,借助其uv和cmr光谱证明了所得化合物的结构。
