Disclosed is a method of making 2-substituted-2-halo-1,3-propanediols via reduction of corresponding malonate compounds. Also disclosed is a method of making 2-substituted-2-halo-1,3-dicarbamate compounds (such as halo derivatives of felbamate, including fluorofelbamate) via reduction of malonate compounds, followed by carbamoylation. Reduction of the malonate compounds is carried out using an electrophilic hydride reagent.
公开了一种通过还原相应的丙二酸酯化合物制备2-取代-2-卤代-1,3-丙二醇的方法。还公开了一种通过还原丙二酸酯化合物,然后进行羰酰化的方法制备2-取代-2-卤代-1,3-二氨基甲酸酯化合物(如费巴酯的卤代衍生物,包括氟费巴酯)。丙二酸酯化合物的还原是使用亲电性氢化试剂进行的。
