5-Aryl-2-oxazolidinones have been synthesized readily by the elimination of dimethylamine from the corresponding (2-hydroxyethyl)ureas. The ureas are obtainable by the photoreaction of tetramethylurea with para-substituted benzaldehydes (Method A) or with para-substituted methyl benzoates (Method B). The electronic character of the substituent on the benzene ring determines which method is suitable
5-Aryl-2-oxazolidinones 很容易通过从相应的(2-羟乙基)脲中消除二甲胺来合成。脲可通过四甲基脲与对位取代苯甲醛(方法 A)或对位取代苯甲酸甲酯(方法 B)的光反应获得。苯环上取代基的电子特性决定了哪种方法适合制备(2-羟乙基)脲。
