Abstract: 4-(N-Boc-amino)-1,2,3-triazole-5-carbaldehydes upon heating under reflux in acetic acid in the presence of pyrrolidine react with cycloalkanones, acetylacetone, 1,3-cyclohexanediones, and malononitrile resulting in annulation of the pyridine ring with the formation of new derivatives of [1,2,3]triazolo[4,5-b]pyridine. read more here.

Abstract: New triazolo[1,5-a]pyrimidines containing aroyl and acetyl or ester groups in the pyrimidine ring were synthesized in a process related to the Biginelli-like reaction, using hydrates of arylglyoxals, β-dicarbonyl compounds, and 1H-1,2,4-triazol-5-amine. Reaction was carried out… read more here.
