SYNTHESIS AND STRUCTURE OF HYDRAZONES OBTAINED FROM HYDRAZIDES OF [5-(4-PYRIDYL)-1,3,4-OXADIAZOL-2-YLTHIO]ACETIC OR 2-[5-(4-PYRIDYL)-1,3,4-OXADIAZOL-2-YLTHIO]PROPIONIC ACIDS

Abstract

It has been shown by ¹H NMR spectroscopy that hydrazones obtained by the condensation of hydrazides of [5-4-pyridyl)-1,3,4-oxadiazol-2-ylthio]acetic or 2-[5-(2-pyridyl)-1,3,4-oxadiazol-2-ylthio]propionic acids with aldehydes, ketones, and β-dicarbonyl compounds exist in DMSO solution as a mixture of stereoisomeric forms.
