    摘要: A process for preparing optically active hydantoins having the general formula (II): ##STR1## wherein R.sup.1 and R.sup.2, which are different from each other, are independently alkyl group, aralkyl group, aryl group, substituted alkyl group, substituted aralkyl group, or substituted aryl group, or R.sup.1 and R.sup.2 form an asymmetric cyclic compound, characterized in that one configuration of racemic N-carbamoyl-.alpha.-amino acid having the general formula (I): ##STR2## wherein R.sup.1 and R.sup.2 are as above, is enzymatically converted into the corresponding hydantoins.The present invention provides a process for an optical resolution with a high efficiency which can be used for the synthesis of (S)-6-fluoro-spiro-[chroman-4,4'-imidazolidine]-2',5'-dione (USAN; Sorbinil), which is an optically active hydrantoins attracting public attention as a preventive or a remedy for the particular chronic symptoms of diabetes such as cataract and neuropathy, and (S)-.alpha.-methyl-3,4-dihydroxyphenylalanine (L-methyldopa), which is an optically active amino acid widely used as antihypertensives. Further, the present invention provides a novel finding that N-carbamoyl-.alpha.-amino acid having no hydrogen atom on its .alpha.-carbon atom can be biochemically converted into hydantoins by an enzymatic cyclization reaction.

    摘要: With respect to reduced coenzyme Q10, there has been no report about the presence of crystal polymorphism, and it has been considered that a conventionally obtained crystal form is only one form. The present invention relates to a reduced coenzyme Q10 crystal having an endothermic peak indicating melting at 54±2° C. during temperature rise at a rate of 5° C./min by differential scanning calorimetry (DSC), and/or to a reduced coenzyme Q10 crystal showing characteristic peaks at diffraction angles (2θ±0.2°) of 11.5°, 18.2°, 19.3°, 22.3°, 23.0° and 33.3° by powder X-ray (Cu—Kα) diffraction. The crystal form is a novel reduced coenzyme Q10 crystal which has a higher melting point and a lower solubility in a solvent, and is more excellent in stability than the conventionally known reduced coenzyme Q10 crystal.
