    Abstract: PROBLEM TO BE SOLVED: To provide an enzymatic or nonenzymatic method for producing 3-methylamino-1-(thien-2-yl)propan-1-ol represented by formula (I), and further, to provide an enzyme for conducting the method, a nucleic acid sequence encoding the enzyme, an expression cassette including the nucleic acid sequence, a vector and a recombinant host organism.
    SOLUTION: The method comprises the following processes: (a) thiophene is reacted with a halogenated β-halopropionyl or halogenated acryloyl in the presence of a Lewis acid; wherein, either simultaneously or after the reaction but prior to isolating a reaction product, a hydrogen halide is passed through the reaction product to obtain a 3-halo-1-(thien-2-yl)propan-1-one; and (b) the propanone obtained in the step (a) is reduced, and subsequently, the reduced product is reacted with methylamine without isolating the reaction product as appropriate.

    Abstract: The invention relates to a method for preparing optically active 2-hydroxy acid ester derivatives of the formula R1-C(OH)-C(O)-O-R2 (I),comprising the bringing into contact of 2-oxo acid ester derivatives of the formula R1-C(O)-C(O)-O-R2 (II) with an enzyme (E) selected from the class of dehydrogenases, in the presence of reduction equivalents, where the compound of the formula (II) is enzymatically reduced to the compound of the formula (I), and the reduction equivalents consumed in the course of the reaction are regenerated again by converting a reducing agent (RA) to the corresponding oxidation product (OP) with the help of the enzyme (E). The invention further comprises a dehydrogenase which reduces 2-oxo acid esters in the presence of reduction equivalents to the corresponding S- 2-hydroxy acid esters, and also a nucleic acid encoding the dehydrogenase.
