Synthesis of Some New 1,2,4-Triazine and 1,2,5-Oxadiazine Derivatives with Antimicrobial Activity

Abstract EN

1,2,4-Triazine and 1,2,5-oxadiazine derivatives 2–12 were obtained from treated 1,3-oxazolone (1) with phenyl hydrazine or hydroxylamine hydrochloride.

Chlorotriazine derivative 3 undergoing condensation reactions with different reagents produced new fused tetrazolo-triazine and triazino-quinazolinone derivatives.

1,2,5-Oxadiazine has been used as a synthon for the fused pyrazolo-oxadiazine derivative.

The constitution of the prepared compounds was built up based on microanalytical and spectral data.

Some of the new compounds were assessed for their antimicrobial activity.
