Reaction of hydrazonoyl halides 49 1: Synthesis and antimicrobial activity of some new pyrimido[1,2-b][1,2,4,5]tetrazin-6-one, tetrazino[3,2-b]quinazolin-5-one, pyrimidino[1,2-b]1,2,4,5-tetrazin-5-one and triazolo[4,3-a]pyrimidine derivatives

摘要

Pyrimido[l,2-ft][l,2,4,5]tetrazin-6-one, tetrazino[3,2-b]quinazolin-5-one, pyrimidino[ 1,2-b] 1,2,4,5-tetrazin-5-one and triazolo[4,3-a]pyrimidine derivatives were synthesized from C-(4-methyl-2-phenyl)thiazol-5-oyl-A'-phenyl-hydrazonoyl bromide and different pyrimidine-2-thiones. New compounds had their structures confirmed hy elemental and spectral analysis and were screened antimicrobial activity.
