Application of a very mild protocol to the Beckmann rearrangement of ketoximes of pyrazolo annulated oxocarbazole 5a and oxoazacarbazole 5b with the organocatalyst derived from 2,4,6-trichloro[1,3,5]triazine (TCT) and dimethylformamide (DMF) has been explored to provide a regioselective formation of the corresponding azepine 6a and 1,4-diazepine 6b respectively in good yield and purity. The mechanistic precedence for the exclusive formation of only one regioisomer has been discussed. Copyright Taylor & Francis Group, LLC.
