Highly pure optically active threo-3-amino-1,2-epoxy compounds appropriate for materials for manufacturing drugs and a process for producing the same on an industrial scale. An optically active threo-3-amino-1,2-diol derivative is subjected in an organic solvent in the presence of a base to alkylsufonylation or arylsulfonylation to thereby give the corresponding optically active threo-3-amino-2-hydroxy-1-sulfonyloxy compound. Next, the resultant product is subjected to epoxidation in the presence of a base to give the corresponding optically active threo-3-amino-1,2-epoxy compound. The thus obtained epoxy compound is purified by using an organic solvent and water, thus giving a highly pure epoxy compound.
适用于制造药物材料的高纯度光学活性苏氨酰-3-氨基-1,2-环氧化合物及其工业化生产方法。光学活性苏氨酰-3-氨基-1,2-二醇衍生物在有机溶剂中,在碱存在下进行烷基磺酰化或芳基磺酰化,从而得到相应的光学活性苏氨酰-3-氨基-2-羟基-1-磺酰氧基化合物。接着,将得到的产物在碱存在下进行环氧化反应,得到相应的光学活性苏氨酰-3-氨基-1,2-环氧化合物。由此得到的环氧化合物通过使用有机溶剂和水进行纯化,从而得到高纯度的环氧化合物。
