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
