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.

By PMR spectroscopy it was shown that the benzoylhydrazones of methyl 4-aryl-2,4-dioxobutyrates exist in deuterochloroform solutions as tautomeric mixtures of the configurational isomers of the ketohydrazone and cyclic 5-hydroxypyrazoline forms.The equili
