The reaction of 1,3,5-triketones and arylhydrazines provided indolylpyrazole derivatives in a one-pot reaction in good to moderate yields. Both the pyrazole and indole rings were constructed simultaneously with phenylhydrazine, $RCOCH_2CO$- moiety for the pyrazole and the remaining -$CH_2COR$ part for the indole ring.

The triketones 3-6 were obtained by alkylation of cyclopentanone or cyclohexanone with the appropriate cycloalkanone bis-mannich base (1) or (2). Schmidt reaction of the tricketones 3-6 afforded the corresponding trcyclic lactames 7-10 respectively. reduction of 7 and 9 gave compounds 11 and 12 respectively.
