Synthesis, reactions, and antimicrobial activity of some novel pyrazolo[3,4-d]pyrimidine, pyrazolo[4,3-e][1,2,4]triazolo[1,5-c]pyrimidine, and pyrazolo[4,3-e][1,2,4]triazolo[3,4-c]pyrimidine derivatives

Treatment of N-phenyl-substituted benzenecarbo-hydrazonoyl chlorides 1a-d with malononitrile in sodium ethoxide solution gave 5-amino-4-cyanopyrazole derivatives 2-5. Compounds 2-5 were converted to formidate derivatives 6-9 upon treatment with TEOF in ac

A new strategy for the synthesis of pyrazolo[4,3-e][1,2,4]triazolo[4,3-c]pyrimidines and pyrazolo[4,3-e][1,2,4]triazolo[1,5-c]pyrimidines

A series of pyrazolo[4,3-e][1,2,4]triazolo[4,3-c]pyrimidines were prepared via oxidative cyclization of aldehyde N-(1,3-diphenylpyrazolo[3,4-d]pyrimidin-4-yl)hydrazones. Dimroth rearrangement of such a series yielded pyrazolo[4,3-e][1,2,4]triazolo[1,5-c]p
