A series of asymmetric semicarbazides were synthesised using 3-coumarin isocyanate, which was prepared from 3-coumarinyl azide by Curtius rearrangement, with acid hydrazides under microwave irradiation using a one-pot procedure. This method has the advantages of mild conditions, easy handling and high yields. The products, which have been characterised by analytical and spectral data, have many medicinal
使用 3-香豆素异氰酸酯合成了一系列不对称氨基脲,该异氰酸酯由 3-香豆素基叠氮化物通过 Curtius 重排与酸酰肼在微波辐射下使用一锅法合成。该方法具有条件温和、易操作、收率高等优点。已通过分析和光谱数据表征的产品具有许多医药和农业化学应用。
