## Abstract In this paper we report that the title compound (3) reacts with excess __N,N__‐dimethylformamide (DMF) containing two equivalents of acetic acid to afford 6‐amino‐1,2,4‐triazolo[3,4‐__f__][1,2,4]triazin‐8(7__H__)‐one (**1**). When 3‐amino‐2‐benzyl‐6‐hydrazino‐1,2,4‐triazin‐5(2__H__)‐one
Two new glycosyl amino acids N'~-Fmoc-Ser[Ac4-fl-D-Galp-(1 ~ 3)-Ac2-a-D-GalN3P]-OPf p and N'~-Fmoc-Thr[Ac4-/3-D-Galp-(1 ~ 3)-Ac2-a-D-GalN3p]-OPf p were synthesized. Glycosylation of N'~-Fmoc-Ser-OPf p or N ~-Fmoc-Thr-OPfp with protected/3-o-Gal-( 1 -~ 3)-D-GaIN 3 donors afforded the glycosyl amino a
