β-Substituted furane derivatives such as N-(4-R-phenyl)-5-nitro-3-furanecarboxamides (Ia-Ij) have been prepared by the reaction of 5-nitro-3-furanoyl chloride with 4-R-anilines (R = H, CH3, OCH3, N(CH3)2, Cl, Br, NHCOCH3, CN, COOCH3, NO2): The structure of the compounds synthesized has been confirmed by their IR, UV, 1H NMR and mass spectra.
β-取代呋喃衍生物如N-(4-R-苯基)-5-硝基-3-呋喃羧酰胺(Ia-Ij)已通过5-硝基-3-呋喃酰氯与4-R-苯胺(R = H,CH3,OCH3,N(CH3)2,Cl,Br,NHCOCH3,CN,COOCH3,NO2)的反应制备:合成化合物的结构已通过它们的红外光谱、紫外光谱、1H核磁共振和质谱得到确认。
