Application of Beckmann rearrangement in the synthesis of indophenazino fused pyrrolo [3,2-c] azepine and pyrrolo [3,2-c] diazepine derivatives

Author(s): Veena Yadav, Nishant Yadav, Meenakshi Agrawal and D. Kishore

A variety of ketoximes of indophenazino fused carbazole 5a and azacarbazoles 5(b-e), easily prepared from the corresponding ketones 4(a-e) undergo the Beckmann rearrangement upon treatment with 2,4,6-trichloro [1,3,5] triazine in N,N-dimethylformamide at room temperature afforded indophenazino fused pyrrolo [3,2-c] azepine (6a) and indophenazino fused pyrrolo [3,2-c] diazepines derivatives 6(b-e) in moderate to goog yields.
