Abstract

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.

确定 2-硝基呋喃-3-羧酸肼构型的核过豪瑟效应

利用一维和二维 1H、13C NMR 光谱研究了 4-乙酰基-5-甲基-2-硝基呋喃-3-甲酸酯与取代肼相互作用得到的 4-乙酰基-2-硝基呋喃-3-甲酸酯肼的结构。根据 1H-1H NOESY 数据，研究中的肼以 E 构型存在，X-射线衍射分析证实了这一点。
