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, RCOCH2CO- moiety for the py

C(α),O-Dilithiooximes, C(α),N-dilithiophenylhydrazones, or C(α),N-dilithioacylhydrazones were prepared in an excess of lithium diisopropylamide (LDA) and condensed with a variety of esters followed by acid-cyclization to give substituted isoxazoles and pyrazoles.
