Abstract

The present invention concerns a method for the preparation of 2,4- dihydroxybutyric acid from homoserine comprising a first step of conversion of the primary amino group of homoserine to a carbonyl group to obtain 2-oxo-4- hydroxybutyrate and a second step of reduction of the obtained 2-oxo-4- hydroxybutyrate (OHB) to 2,4-dihydroxybutyrate
