A Two-Step Synthesis of 1H-Tetrazolyl-1H-1,4-benzonitriles and 1H-Tetrazolyl-benzo[b][1,4]diazepines

Abstract A two-step synthetic protocol for the title heteroannulated diazepines has been developed. The approach includes a pseudo five-component isocyanide-based condensation reaction between diamines, ketones, isocyanides and trimethylsilyl azide and proceeds in good yields.
