The present invention is related to azole derivatives notably for use as pharmaceutically active
compounds, as well as to pharmaceutical formulations containing such azole
derivatives. Said azole derivatives are modulators of the protein kinase signalling
pathways, particularly the one involving c-Jun N-terminal kinase and/or Glycogen
Kinase Synthase 3. The present invention is furthermore related to novel azole
derivatives as well as to methods of their preparation. X is O, S or NR0,
with R0 being H or an unsubstituted or substituted C1 -C6
alkyl; A is 2-pyridyl, 3-pyridyl, 4-pyridyl, pyridazinyl, pyrimidinyl, pyrazinyl
or triazinyl group.

7-Hydroxy-3-phenoxy-8-formylchromones were synthesized using the Duff reaction and were reacted with 2,4-dinitrophenylhydrazine to produce hydrazones and with an excess of hydrazine hydrate to produce the pyrazole recyclization products. Derivatives of α-pyrono[2,3-f]chromones were synthesized using the Knoevenagel condensation with 2-azahetarylacetonitriles and the Perkin reaction.

Synthesis of novel 3‐substituted‐1,2,3‐triazolo[1,5‐a]quinazolinones in high yields was performed via anionic hetero‐domino reaction of appropriate substituted 2‐azidobenzoates prepared from isatines and acetonitriles activated by 1,3‐thiazole, 1,3‐benzothiazole, 1,3,4‐oxadiazole, and 1,2,4‐oxadiazole rings. It was shown that acetonitriles exhibited high reactivity and were convenient methylenic compounds

Abstract Unsymmetrical azines were synthesized from reaction of C-coumarinoyl-N-arylformohydrazonoyl bromide with different alkyl carbodithioates. In addition, reactions of hydrazonoylhalides with thioanilide and methyl dithioates were studied. The structures of newly synthesized compounds were confirmed by elemental analyses, spectroscopic tools, and alternative syntheses whenever possible.
