The ribonucleosides of pyrazolo (5, 4-e)-1, 2, 4-triazine derivatives derivatives were synthesized. The α, β-isomes were distinguished with 1H NMR. β-isomer was the major product in acetyl protected ribonucleosides. In benzoyl protected ribonucleosides, no α-isomer was formed. The JH^1H^2 of cis isomer was bigger than that of trans in five membered ring.
