Abstract:

Synthesis of pyrazolylcarbazoles and pyrazolinylcarbazoles is reported. Phenylhydrazones of acylcarbazoles furnished pyrazolylcarbazoles under Vilsmeier conditions. Carbazolylchalcones on treatment with hydrazine in acetic acid furnished pyrazolinylcarbazoles.

Keywords: heteroarylcarbazoles, vilsmeier reaction, acyl carbazoles, carbazolylchalcones, pyrazolylcarbazoles, pyrazolinylcarbazoles
