Ethyl 1-aminotetrazole-5-carboxylate (1) has been utilized to construct a variety of novel tetrazolo [1,5-b]-1,2,5-oxadiazepine derivatives which repesent a relatively little explored group with interesting antibacterial activities. The synthesized compounds were elucidated using IR, $^1H$ NMR and mass spectroscopic methods, besides elemental analyses.
