摘要

The structure of 4-acetyl-2-nitrofuran-3-carboxylates hydrazones obtained from the interaction of 4-acetyl-5-methyl-2-nitrofuran-3-carboxylates with substituted hydrazines was studied using 1D and 2D 1H, 13C NMR spectroscopy. According to 1H–1H NOESY data, it was shown that the hydrazones under consideration exist in the E-configuration, confirmed by X-ray diffraction analysis.
