C(α),N-Thiosemicarbazones or C(α),N-semicarbazones were polylithiated with excess lithium diiso-propylamide, and the resulting cyclized intermediates were condensed with aromatic esters to afford N-(1H-pyrazol-3-yl)arylamides. The polylithiated int

C(α), N-Hydrazones of hydrazinecarboxylic acid, 1, 1-dimethylethyl ester [C(α), N-carbo-t-butoxyhydrazones] were metalated with excess lithium diisopropylamide, and the dianion-type intermediates were condensed with select aromatic esters followed

2-, 3-, or 4-Picolyllithium was prepared in excess lithium diiso-propylamide and condensed with several hydroxy-benzaldehydes and 4-hydroxy-acetophenone to afford substituted hydroxyphenyl-pyridyl-ethanols and α-hydroxyphenyl-α-methylpyridineethano
