Abstract (en)
[origin: WO2012175837A1] The subject of the invention is the use of an organometallic compound for the implementation of a process for preparing chiral derivatives consisting of phospho a- or ß-amino acids and also derivatives thereof with enantiomeric excesses of at least 50%, by reacting a starting product consisting of an a- or ß-dehydroamino phosphoester with an organometallic compound, in the presence of a catalyst containing a transition metal and a chiral ligand, at a temperature that varies from -20°C to 90°C.
