Abstract: Reactions of primary and secondary alcohols with N'-[2-oxo-5-R-furan-3(2H)-ylidene]acylhydrazides resulted in the furan ring decylization toform 2-[2-(arylcarbonyl)hydrazinylidene]-4-alkyl esters of R-4-oxobutanoicacids.

Hydrazides reacted with acylpyruvic acid esters possessing a terminal straight chain alkyl substituent at the C=O bond distal from the ester group, giving 5-hydroxy-2-pyrazolines. Acylpyruvates with bulky terminal substituents underwent condensation at the C=O bond adjacent to the ester group, giving products with hydrazone or 5-hydroxy-2-pyrazoline structure and capable of displaying ring-chain equilibrium between these tautomers in solution.
