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.
