摘要
The synthesis of benzo[b]azepines using protonated aminating reagent (MsONH3OTf) and alkynes through I2- mediated [6 + 1] annulation reaction has been developed. This protocol features excellent functional group tolerance and mild reaction conditions and affords the benzo[b]azepines in moderate to good yields under metal-free reaction conditions.
