[3+2] Cyclization of Azidotrimethylsilane with Quinoxalin‐2(1H)‐Ones to Synthesize Tetrazolo[1, 5‐a]quinoxalin‐4(5H)‐Ones. Issue 23 (30th October 2018) - Yang, Qiming
Abstract: A convenient and efficient protocol for the synthesis of thetetrazolo[1, 5‐ a ]quinoxalin‐4(5 H )‐ones via copper‐catalyzed [3+2] cyclization of azidotrimethylsilane with quinoxalin‐2(1 H )‐ones under mild conditions has been disclosed. This practical protocol is compatible with a variety of functional groups and provides an access to functionalized tetrazolo[1, 5‐ a ]quinoxalin‐4(5 H )‐ones from readily available and safe starting materials.
