Novel 3-acetyl-2-aminothiophenes were prepared from cyanoacetone and1,4-dithianyl-2,5-diols using a modified Gewald reaction. The syntheses of thecorresponding acetamides, as well as that of 3-acetyl-2-amino-5-nitrothiophene – aninteresting building-block for thiophene azo dyes – are reported. Detailed spectroscopicinvestigations (1H-NMR, 13C-NMR, MS, IR) of the obtained compounds are presented.
利用改良的格瓦尔德反应,从氰基丙酮和 1,4-二噻烷-2,5-二醇制备了新型 3-乙酰基-2-氨基噻吩。报告了相应的乙酰胺以及 3-乙酰基-2-氨基-5-硝基噻吩(噻吩偶氮染料的一种有趣的构建基块)的合成。报告还介绍了所获化合物的详细光谱研究(1H-NMR、13C-NMR、MS、IR)。
