A new approach for the synthesis of arrays of bifunctional tricyclic tetrazole-1H-benzo[b][1,4]diazepines has been investigated. It includes a sequential two-step isocyanide-based condensation reaction of diamines or 2-nitroanilines, ethyl 3-oxobutanoate or 2,2,6-trimethyl-4H-1,3-dioxin-4-one, isocyanides and trimethylsilyl azide in good yields.
