The object of the present invention is to provide
3-hydroxy-3-(2-thienyl)propionamides useful as synthesis intermediates of
pharmaceutical preparations and the like and a method for obtaining
optically active 3-amino-1-(2-thienyl)-1-propanols using the same with
high reaction yield, high optical yield and industrially low
cost.According to the present invention,
3-amino-1-(2-thienyl)-1-propanols are obtained by carrying out asymmetric
reduction of a .beta.-ketocarbonyl compound having thiophene ring in the
presence of a catalyst constituted from a compound of a group VIII or IX
metal in the periodic table (e.g., a ruthenium compound) and an
asymmetric ligand represented by a specified optically active diamine
derivative (e.g., a diphenylethylenediamine derivative), or using a cell,
a treated product of said cell or the like of a microorganism, and as
occasion demands, carrying out amidation of the ester group and then
carrying out reduction of the amido group. ##STR00001## (each of the
substituents is as described in claim 1).
