Synthesis of New Derivatives of Pyrimido[4,5-e][1,2,4]triazolo[4,3b][1,2,4]triazine
the corresponding pyrimido[4,5e][1,2,4]triazolo[4,3-b][1,2,4]triazine3(a-c) in good yields.The structure of all the new synthesized compounds were confirmed by their spectral and microanalytical data....
Synthesis of new derivatives of pyridazino[6,1-c]pyrimido[5,4-e][1,2,4]triazine
quantitatively the desired heterocyclized pyridazino[6,1 c]pyrimido[5,4e][1,2,4]triazine derivative as a novel heterocyclic system. Eventually, the reaction of it with various secondary amines obtained new derivatives of pyridazino[6,1c]pyrimido[5,4 e][1,2,4...
Synthesis of 1,2,4-Triazolo[1,5-d]-1,2,4-triazine-5-thiones
In an attempt to discover bicyclic compounds containing the 1,2,4-triazine moiety, 1,2,4-triazolo[1,5-d]-1,2,4-triazine-5-thiones from one pot reaction of arylnitriles with 4-amino-1,2,4-triazine-3-thione-5-one in the presence of potassium tert...
Synthesis of some derivatives of pyrimido[5,4-e]tetrazolo[5,1-c][1,2,4]triazine; a novel heterocyclic system
Several new derivatives of pyrimido[5,4-e]tetrazolo[5,1-c][1,2,4]triazine have been synthesised through the reaction of 5-hydrazinyl-1H-tetrazole with 5-bromo-2,4-dichloro-6-methylpyrimidine in CHCl3 solution at ambient conditions. Further treatment...
Synthesis of new derivatives of pyridazino[6,1-c]pyrimido[5,4-e][1,2,4]triazine; a novel heterocyclic system
Several derivatives of the novel pyridazino[6,1-c]pyrimido[5,4-e][1,2,4]triazine ring system have been synthesised through heterocyclisation of 5-bromo-2,4-dichloro-6-methylpyrimidine with 3-chloro-6-hydrazinylpyridazine followed by treatment...
Synthesis of new heterocyclicsystem of [1,2,4]triazolo[4 ,3 :1 ,6 ]pyrimido[4 ,5 :3,4]pyridazino[1,6- d][1,2,4]triazine
aromatic aldehydes in boiling ethanol and then oxidative heterocyclization of the corresponding imines in an appropriate solvent yielded the corresponding novelheterocyclic system of [1,2,4] triazolo[4,3:1,6]pyrimido[4,5:3,4]pyridazino[1,6d][1,2,4]triazine...
