We have developed a synthetic route for (2S,3R)- and (2S,3S)-[2-C-13;3-H-2] glutamic acids with high enantioselectivity. The key reactions in this synthesis are the asymmetric reduction of the 2,3-didehydro-ornithine derivative using the (S,S)-Et-DuPHOS-Rh catalyst and the oxidation of the delta-position by ruthenium catalysis.
