Résumé
A one pot synthesis in five steps of immediate precursors of new transition state analogues of enzymatic transcarbamylation reactions, N-[(phosphinylmethyl)phosphonate]-L-aspartate and N-[(phosphinylmethyl)phosphonate]-L-ornithine is described.An efficient synthesis of immediate precursors of new transition state analogues of enzymatic transcarbamylation reactions, N-[(phosphinylmethyl)phosphonate]-L-aspartate and N-[(phosphinylmethyl)phosphonate]-L-ornithine is described.
