A new synthesis of poly heterocyclic compounds: Expected anti-cancer reagents

In this articale, we have described a new practical cyclocondensation synthesis for a series of [1,2,4]triazolo[4,3-c]pyrido[3,2-e] pyrimidine and pyrido[2′,3′:4,5] pyrimido[6,1-c][1,2,4] triazine from 2-amino-3-cyano-4.6-diarylpyridines. Also polyheterocyclic compounds containing [1,2,4]triazolo and [1,2,3,4]tetrazolo moieties were also synthesized through the reactions of 3-hydrazino-8,10-diaryl [1,2,4]triazolo[4,3-c]pyrido[3,2-e]pyrimidine with both formic acid and the formation of diazonuim salt respectively . Newly synthesized heterocycles…
