| titleOfInvention | Method for producing compound having hydantoin ring |
| abstract | The object of the present invention is to improve the sin body purity of a compound having a hydantoin ring that is important as an optical material, an electronic material, a pharmaceutical and agrochemical raw material and an intermediate, a diagnostic drug raw material and an intermediate. The following (Z) -2-benzyloxy-5,7-diazaspiro [3,4] octane-6,8-dione having a hydantoin ring is mixed with water or a mixed solvent of water and a polar solvent. By using it for crystallization, a syn isomer is selectively obtained. [Chemical 1] [Selection figure] None |
