    Abstract: A process for preparing optically active alcohols of the formula Ia or Ib in which R1,R2 are alkyl, alkenyl, aryl, or alkylaryl groups which may in turn be substituted one or more times by alkyl, halogen, SH, SR2, OH, OR2, NO2, CN, CO, COOR2, NR2R3 or NR2R3R4+X, where R2, R3 and R4 are independently of one another H or a lower alkyl or lower alkoxy radical, and X−is a counter ion, with the proviso that R1 is not equal to R2, by reducing the corresponding ketone, where the reduction is carried out with a dehydrogenase having the polypeptide sequence of SEQ ID NO: 2 or NO: 4, or with a polypeptide sequence in which up to 25% of the amino acid residues are altered by comparison with SEQ ID NO: 2 or NO: 4 by deletion, insertion, substitution or a combination thereof.

    Abstract: Método para la producción de (S)-3-metilamino-1-(tien-2-il)-propan-1-ol de la fórmula I-S en el cual a) reacciona tiofeno con un halogenuro de ß-halopropionilo o un halogenuro de acriloilo en presencia de un ácido Lewis para dar una 3-halo-1-(tien-2-il)-propan-1-ona, donde se introduce un haluro de hidrógeno simultáneamente o después de terminada la reacción, aunque antes del aislamiento del producto de reacción, y b) se reduce la propanona obtenida en la etapa a) en presencia de una deshidrogenasa (E.C. 1.1.x.x.), la cual exhibe una selectividad respecto a la formación de (S)-3-metilamino-1-(tien-2-il)propan-1-ol, y a continuación, dado el caso, se hace reaccionar con metilamina sin aislamiento del producto de reacción.
