Herein we present the synthesis of several new hydrazino derivatives of cyclopenta[c]pyridine, 5,6,7,8-tetrahydroisoquinoline and pyrano[3,4-c]pyridine from 3-oxo-4-cyano fused pyridine derivatives. The hydrazino derivatives obtained were used as starting materials for the synthesis of isomeric triazolopyrimidines as well as tetrazolopyrimidines. Furthermore, the rearrangement of triazolopyrimidines
本文中,我们从3-氧代-4-氰基稠合的吡啶衍生物合成了几种新的环戊基[ c ]吡啶,5,6,7,8-四氢异喹啉和吡喃[3,4- c ]吡啶的肼衍生物。获得的肼基衍生物用作合成异构的三唑并嘧啶和四唑并嘧啶的起始原料。此外,还提出了将三唑并嘧啶7重新排列为三唑并嘧啶8。在DMSO中,四唑并嘧啶10与相关的叠氮嘧啶9处于平衡状态。。通过X射线晶体学证实了四唑并嘧啶的结构。测试合成的化合物的抗微生物活性。
