Abstract

PIDA/TBAB-promoted oxidative geminal diazidofunctionalization of alkynes has been described for the first time. The transformation demonstrates a mechanistically distinctive approach to access geminal diazides, in which TBAB plays a crucial role as brominating agent and for the in situ generation of tetrabutylammonium azide. Furthermore, we have demonstrated here the first cycloaminative strategy by tactically employing the two azides groups leading to quinoxalines and synthesis of bis-triazole derivatives via copper catalysis.
