Abstract

  • 2'-Hydroxyacetophenone phenylhydrazone was trilithiated with excess lithium diisopropylamide, and the resulting trianion-type intermediate was condensed with a variety of aromatic esters followed by acid cyclization to 2-(1-phenyl-5-phenyl or 5-substituted phenyl-1H-pyrazol-3-yl)phenols.
