The synthesis of 2‐thioxoquinazolinone derivatives was achieved by condensation of isatoic anhydride, primary amine, and carbon disulfide under microwaveirradiation. This convenient and efficient method affords the desired products with good to excellent yields. Satisfactory infrared spectroscopy, 1H NMR, and high‐resolution mass spectrometry (electrospray ionization) spectra were obtained for all
在微波辐射下,通过等规酸酐,伯胺和二硫化碳的缩合反应,可以合成2-硫代氧杂喹唑啉酮衍生物。这种方便而有效的方法可提供所需的产品,并具有良好或极好的收率。对于上述所有化合物,均获得了令人满意的红外光谱,1 H NMR和高分辨率质谱(电喷雾电离)光谱。
