The preparation of 2-(1-phenyl-5-phenyl or 5-substituted phenyl-1H- pyrazol-3-yl)phenols from trilithiated 2'-hydroxyacetophenone phenylhydrazone and aromatic esters

Article abstract of DOI:10.1080/00397919908085792

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-substitute
