English

a process for producing (r)-tetrahydrothiophen-3-ol, comprising the step (a) of incubating tetrahydrothiophen-3-one in the presence of a preparation of strain belonging to the genus penicillium, the genus aspergillus or the genus streptomyces or cultured cells thereof, which preparation is capable of biological conversion of tetrahydrothiophen-3-one to (r)-tetrahydrothiophen-3-ol, and the step (b) of collecting (r)-tetrahydrothiophen-3-ol from the incubation solution. there is further provided a method of crystallizing optically active tetrahydrothiophen-3-ol of enhanced optical purity, characterized in that the optically active tetrahydrothiophen-3-ol is crystallized in an organic solvent whose temperature is 1°c or below.

French

l'invention concerne un procédé de production de ( r)-tétrahydrothiophén-3-ol comportant les étapes suivantes : (a) incubation de tétrahydrothiophén-3-ol en présence d'une préparation de souches appartenant au genre penicillium, genre aspergillus ou genre streptomyces ou leurs cellules cultivées, cette préparation permettant la conversion biologique de tétrahydrothiopén-3-one en ( r)-tétrahydrothiopén-3-ol, et (b) collecte de ( r)-tétrahydrothiophén-3-ol à partir de la solution d'incubation. l'invention concerne également un procédé de cristallisation de tétrahydrothiophén-3-ol optiquement actif de pureté optique améliorée. l'invention est caractérisée en ce que le tétrahydrothiophén-3-ol optiquement actif est cristallisé dans un solvant organique d'une température de 1 °c maximum.
