Selective iodocyclization of 6‐(alkenylamino)‐1‐allylpyrazolo[3,4‐d ]pyrimidines provided hydrogenated derivatives of 1‐allyl‐8(9)‐iodomethylimidazo(pyrimido)[1,2‐a ]pyrazolo[4,3‐e ]pyrimidines which were further reacted with NaN3 at 75°С to 80°С to give a series of new‐type 1,3,6‐triazocines annulated with the pyrazole, pyrimidine, imidazole (or pyrimidine), and 1,2,3‐triazole rings. The compounds
6-(烯基氨基)-1-烯丙基吡唑并[ 3,4- d ]嘧啶的选择性碘环化提供了1-烯丙基-8(9)-碘甲基咪唑并(pyrimido)[1,2- a ]吡唑并[4,3- e ]嘧啶,在75°C至80°C下与NaN 3进一步反应,得到一系列新型1,3,6-三唑嗪,与吡唑,嘧啶,咪唑(或嘧啶)和1,2 ,3-三唑环 通过分析,光谱(IR,1 H和13 C NMR,HPLC质量)和X射线衍射数据对合成的化合物进行结构表征。
