The present invention relates to a method for producing optically active 2-(N-substituted aminomethyl)-3-hydroxybutyric acid esters wherein a 2-(N-substituted aminomethyl)-3-oxobutyric acid ester is treated with an enzyme source capable of stereoselectively reducing said ester to the corresponding optically active 2-(N-substituted aminomethyl)-3-hydroxybutyric acid ester having the (2S,3R) configuration. The present invention provides an efficient method for industrially producing optically active 2-(N-substituted aminomethyl)-3-hydroxybutyric acid esters, in particular such compounds having the (2S,3R) configuration, which are useful as intermediates for the production of medicinal compounds, among others.
