A novel and simple approach to the synthesis of sulfonylureas has been reported. It involved the reaction of various amines with diphenyl carbonate to yield the corresponding carbamates, which subsequently reacted with different sulphonamides to produce different sulfonylureas in excellent yields. The first reaction of diphenyl carbonate with amines was carried out in aqueous:organic (H2O:THF, 90:10)
已经报道了一种新颖且简单的合成磺酰脲类的方法。它涉及各种胺与碳酸二苯酯的反应,以产生相应的氨基甲酸酯,其随后与不同的磺酰胺反应,以优异的产率产生不同的磺酰脲类。碳酸二苯酯与胺的第一反应是在室温下于水性:有机(H 2 O :THF,90 : 10)介质中进行的,以生成氨基甲酸酯,该氨基甲酸酯与磺酰胺反应后,直接通向磺酰脲类。上述方法避免了传统的多步骤方案,并且避免使用有害,刺激性,有毒和对水分敏感的试剂,例如光气,异氰酸酯和/或氯甲酸酯。
