2-(2-Methylphenyl)hydrazinecarboxylic acid esters were metalated with excess lithium diisopropylamide, and the resulting polyanion-type intermediates were condensed with aromatic esters followed by acid cyclization to the 3-substituted- 1 (2H)-isoqui

3-Methyl-2-quinoxalinol dianion was prepared in an excess of lithium diisopropylamide (LDA), condensed with select aliphatic or aromatic esters, a carbamyl chloride, or aliphatic carboxylic acid anhydrides, and the resulting intermediates were quench
