Starting from pyrimido[4,5‐e][1,3,4]oxadiazines ( 3a , 3b , 3c ) , a synthetic pathway to [1,2,4]triazolo[4′,3′:1,2]pyrimido[4,5‐e][1,3,4]oxadiazines ( 5a , 5b , 5c , 5d , 5e , 5f , 5g , 5h , 5i ) is described. The reaction of pyrimido[4,5‐e][1,3,4]oxadiazines ( 3a , 3b , 3c ) with hydrazine hydrate afforded the corresponding hydrazino derivatives ( 4a , 4b , 4c ) . Further treatment of these compounds with different orthoesters in acetic acid gave the corresponding [1,2,4]triazolo[4′,3′:1,2]pyrimido[4,5‐e][1,3,4]oxadiazines ( 5a , 5b , 5c , 5d , 5e , 5f , 5g , 5h , 5i ) . Compound ( 3a ) and ( 5b ) , as examples, were tested on different cancer cell lines including HeLa, MCF‐7, and HepG2. Malignant cells were cultured in DMEM medium and incubated with different concentrations of the titled compounds. Cell viability was quantitated by MTT assay. J. Heterocyclic Chem., (2010).
